The toll to a bridge is 2.50. A three-month pass costs $12.00 and reduces the toll to $0.50. A six month pass $37 and permits crossing the bridge for no additional fee. How many crossing per three month period does it take for the three month pass to be the best deal.
c=number of crossings; Q=quarterly pass; S=semi-annual pass; P=pay as you go
P=$2.50c
Q=$12+$0.50c
S=$40
Compare single pay and quarterly ticket:
$2.50c=$12+$0.50c Subtract $0.50c from each side
$2.00c=$12 Divide each side by $2.
c=6 6 crossings is the break even for single pay and quarterly ticket: more crossings favor the ticket.
Compare quarterly and semi-annual tickets:
3 month pro-rated cost of semi annual ticket=$20
$20=$12+$0.50c Subtract 12 from each side
$8=$0.50c Divide each side by $0.50
16=c The break=even point between quarterly and semi annual tickets is 16 crossings per 3 months. More than this favors the semi annual ticket.
ANSWER: The three month pass is the best deal if you cross between 6 and 16 times during the three month period.
I hope this help you

Step-by-step explanation:
8 x 13 = 104
+200
304
Answer:
96feet
Step-by-step explanation:
U want to find displacement
So
Displacement = velocity x time
Velocity = - 8 feet/s ( negative bcuz going down)
Time = 13
Displacement = - 8 x 13
= - 104
Therefore
200 - 104 = 96feet

2y + 8y - 20 = 5 (y -2) simplify
Answer:
y=2
Step-by-step explanation:
2y + 8y - 20 = 5 (y -2)
Combine like terms
10y -20 = 5(y-2)
Divide by 5
10y/5 -20/5 = 5/5(y-2)
2y -4 = y-2
Subtract y from each side
2y-y -4 =-2
y -4 = -2
Add 2 to each side
y-4+4 =-2+4
y =2
Answer:
[tex]2y + 8y - 20 = 5(y - 2) \\ 10y - 20 = 5y - 10 \\ 5y = 10 \\ y = 2 \\ thank \: you[/tex]

What is the inverse of the function f(x) = 2x – 10?
O h(x) = 2x-5
Oh(x) = 2x + 5
Oh(x) =
Ix-5
x) = {x+5
Oh(x) =
If h(x) is the inverse of f(x), then by definition of inverse function, we have
f(h(x)) = x
By definition of f(x), composing f with h gives
f(h(x)) = 2 h(x) - 10
Solve for h(x) :
x = 2 h(x) - 10
2 h(x) = x + 10
h(x) = (x + 10)/2
h(x) = x/2 + 5
