Answer:

A. $80

Step-by-step explanation:

First, let's find the cost of 15 soccer balls.

  • [tex]15*40[/tex]
  • $600

Next, cost of 20 soccer balls.

  • 20 x 40 = 800
  • 15 x 800 = 12000
  • 12000/100 = 120
  • 800 - 120 = 680

Lastly, the difference between 20 and 15 soccer balls:

  • 680 - 600 = $80
80 it’s the answer 80 is the answer
