A computer firm has a team of 46 computer consultants. These individuals either visit firms in the area on pre-arranged visits, or are called in for emergency repairs. The average time spent on each client is 3 hours. The consultants are usually available to work 8 hours a day, 5 days a week. Taking time off and illness into account, their available time reduces by 25%. Calculate the effective capacity of the team (in terms of the number of clients served) for each week. Answer:
The effective capacity of the team, in terms of the number of clients served, is 10 clients per week. To calculate the effective capacity of the team in terms of the number of clients served, we need to consider the available working hours and the average time spent on each client.
The consultants are available to work 8 hours a day, 5 days a week, which totals to 8 hours/day * 5 days/week = 40 hours per week.
Taking into account time off and illness, the available time reduces by 25%. Therefore, the effective working hours per week would be 75% of the total working hours:
Effective working hours = 0.75 * 40 hours/week = 30 hours/week.
Next, we divide the effective working hours per week by the average time spent on each client to find the effective capacity of the team:
Effective capacity = Effective working hours per week / Average time spent on each client
= 30 hours/week / 3 hours/client
= 10 clients/week.
Therefore, the effective capacity of the team, in terms of the number of clients served, is 10 clients per week.

Buffalo Co. recently installed some new computer equipment. To prepare for the installation, Buifalo had some electrical work done in what was to become the server room, costing $18,000. The invoice price of the server equipment was $190,000. Three printers were also purchased at a cost of $1,800 each. The software for the system was an additional $42,000. The server equipment was believed to have a useful life of elght years, but due to the heavy anticipated usage, the printers were expected to have only a four-year useful life. The software to run the system was estimated to require a complete upgrade in five years to avoid obsolescence. Additionally, delivery costs of $10.000 was incurred for all items above. All of the above costs were subject to a 6% non-refundable provincial sales tax During the installation, a training course was conducted for the staff that would be using the new equipment, at a cost of $9.500. Assume that Buffalo follows IFRS, and that any allocation of common costs is done to the nearest 1%(e.8.80%,6%,14%). (b) Assume that Buffalo decides to capitalize the following components of the computer system: server equipment, printers, and software. Calculate the amount to be capitalized for each of these asset groups. (Round percentage to 0 decimal ploces, es. 52%. Round answers to Odecimal places, es. 5,275.)
To capitalize the components of the computer system (server equipment, printers, and software), we need to calculate the amount to be capitalized for each asset group.
To calculate the amount to be capitalized for each asset group, we need to consider the costs that are directly attributable to those assets. In this case, the server equipment, printers, and software are the components to be capitalized.
For the server equipment:
Invoice price of the server equipment = $190,000
Electrical work cost = $18,000
Delivery cost = $10,000
Total costs for server equipment = $190,000 + $18,000 + $10,000 = $218,000
For the printers:
Number of printers purchased = 3
Cost per printer = $1,800
Total costs for printers = 3 * $1,800 = $5,400
For the software:
Software cost = $42,000
Total costs for software = $42,000
Therefore, the amounts to be capitalized for each asset group are as follows:
- Server equipment: $218,000
- Printers: $5,400
- Software: $42,000

q1: Find the hexadecimal representation for each of the following binary numbers:
1. 10101101:
To convert this binary number to hexadecimal, we can group the bits into sets of four from right to left:
1010 1101
Now, we can convert each set of four bits to its corresponding hexadecimal digit:
1010 -> A
1101 -> D
So, the hexadecimal representation of 10101101 is AD.
2. 00100111:
Following the same process as above:
0010 0111
0010 -> 2
0111 -> 7
Therefore, the hexadecimal representation of 00100111 is 27.
q2: Find the decimal representation for each of the following hexadecimal numbers:
1. 8ef:
To convert this hexadecimal number to decimal, we multiply each digit by the corresponding power of 16:
8 x 16² + 14 x 16+ 15 x 1
= 2048 + 224 + 15
= 2287
So, the decimal representation of 8ef is 2287.
2. 5ce:
Similarly:
5 x 16² + 12 x 16 + 14 x 1
= 1280 + 192 + 14
= 1486

53 / 2 = 26 (remainder 1)
26 / 2 = 13 (remainder 0)
13 / 2 = 6 (remainder 1)
6 / 2 = 3 (remainder 0)
3 / 2 = 1 (remainder 1)
1 / 2 = 0 (remainder 1)
Reading the remainders from bottom to top, the binary representation of 53 is 110101.
2. 885:
Following the same process:
885 / 2 = 442 (remainder 1)
442 / 2 = 221 (remainder 0)
221 / 2 = 110 (remainder 1)
110 / 2 = 55 (remainder 0)
55 / 2 = 27 (remainder 1)
27 / 2 = 13 (remainder 1)
13 / 2 = 6 (remainder 1)
6 / 2 = 3 (remainder 0)
3 / 2 = 1 (remainder 1)
1 / 2 = 0 (remainder 1)

You need to subnet a network that has 6 subnets, each with at least 27 hosts. which classful subnet mask would you use?
To subnet a network with 6 subnets, each requiring at least 27 hosts, we need to find a suitable classful subnet mask. In this scenario, we can use a Class B network address, as it provides a large number of host addresses.
A Class B network has a default subnet mask of 255.255.0.0, which allows for 65,534 hosts per subnet. However, this is more than required for each subnet, which only needs 27 hosts. Therefore, we need to subnet further to achieve the desired number of hosts per subnet.
To accommodate at least 27 hosts, we can use a subnet mask of 255.255.255.224, which provides a total of 30 usable host addresses per subnet. This allows for 2^5 - 2 = 30 usable host addresses, where 2^5 is the number of possible host addresses (32) and 2 represents the network address and broadcast address, which cannot be assigned to hosts.
In summary, to subnet a network with 6 subnets, each requiring at least 27 hosts, we can use a Class B network address with a subnet mask of 255.255.255.224.
