If a 25% deposit that has been paid toward the purchase ofa bookshelf is $120, how much more remains to be paid?

If 25% = 120

if 25 is multiplied by 4 to become 100 (%) if we multiply 120 with 4, the answer should be the original cost.

480 is the original cost but since 120 is already paid, the final answer should be 360.

25% = $120

Find 1%

1% = 120 : 25 = $4.80

Find 100% (original price):

100% = 4.8 x 100 = $480

Remaining price to pay:

$480 - $120 = $360

Answer: $360
