Asporting 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?

Retail price of the balls = $1.43 each

Step-by-step 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 + 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 =

  = $1.43

Retail price of the balls will be $1.43.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
