Two eighth-grade classes are selling raffle tickets to raise money. One class is selling tickets for $1.50 each and has already raised $250. The other class
is selling tickets for $4.00 each and has already raised $115. Write an equation which can be used to find , the number of tickets each class needs to sell
so that the total amount raised is the same for both classes.

Answers

Answer:

54 tickets

Step-by-step explanation:

Let the number of tickets to be sold is x.

Then we have:

Class 1 ⇒ 250 + 1.5xClass 2 ⇒ 115 + 4x

Since the amount is same we have the equation:

250 + 1.5x = 115 + 4x

Solving for x:

4x - 1.5x = 250 - 1152.5x = 135x = 135/2.5x = 54

What is perimeter?

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

Perimeter refers to the total outside length of an object,

here, we have,

the length = 4 ft.

so, boundary = perimeter of the square

i.e. 4+4+4+4

=4*4

=16

Hence, The solution is, the boundaries of the indicated value,

4 feet is 16 ft.
