The number is 875

(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:
875
Step-by-step explanation:
lets assume the original amount X
the new amount = X - ( X × 40% )
525 = (60 × X) ÷ 100
X = ( 525 × 100 ) ÷ 60
<u>X = 875</u>
