After buying a pair of sneakers, Ben has $12 left which is 20% of what he started with. How much money did Ben have before he bo

Elis [28]

Answer: $60

Step-by-step explanation:

Given that:

Amount left after purchasing sneakers = $12

$12 is equivalent to 20% of the initial starting amount

Let starting amount = x

20% of x = $12

0.2x = $12

Divide through by 0.2

0.2x / 0.2 = $12 / 0.2

x = $60

Hence, starting amount before buying sneakers is $60
