Answer:

Step-by-step explanation:

Let the amount creating equality = x

10% x + 625 = 20%x                Convert The percentages to a decimal

10/100 x + 625 = 20/100 x       Multiply both sides by 100

10x + 62500 = 20 x                  Subtract 10x from both sides

62500 = 20x - 10x                   Combine

62500 = 10x                             Divide by 10 on both sides

62500/10 =10 x/10

6250  = x

The equality is reached when 6250 sales is made.
