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 buys soccer balls for $5.00 each. What is the retail
price of the soccer balls?

Answer 1

$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
