(525 is equal to a number minus forty percent of a number )

Step Three

Isolate the variable by dividing each side by factors that don't contain the variable.

N = 875

Answer 2

875

Explanation:

lets assume the original amount X

the new amount = X - ( X × 40% )

525 = (60 × X) ÷ 100

X = ( 525 × 100 ) ÷ 60

X = 875
