Question

A sporting goods store marks up the cost s of soccer balls by 250%. Write an expression that represents the retail cost of the soccer balls. The store sells soccer balls for $5.00 each. What is the retail price of the soccer balls?

Answer 1

250÷5=50 Soccer balls

Answer 2

Retail price of the balls = $1.43 each

Explanation:

Cost of the soccer balls = s

Cost of the soccer ball is marked up by 250% then selling price of the balls = s + 250% of s

=
`s+(250)/(100)s`

= s + 2.5s

= 3.5s

So the expression representing selling price of the balls after mark up will be = 3.5s

If selling price of the balls is $5 each then we have to find the retail cost of the soccer balls.

5 = 3.5s

s =
`(5)/(3.5)`

= $1.43

Retail price of the balls will be $1.43.
