Question

An item was marked down 64% from its original price,x . The amount discounted was $30. Which equation can be used to find the original price

Answer 1

OP = discount amount × 100 / discount %

Explanation:

if I understand this correctly, the actual sale price was 36% (100-64) of the originally marked price.

original price (OP) = 100%

64% of OP = 30

1% of OP = 30/64

OP (100%) = 100 × 30/64

this could be simplified to 100 × 15/32, but this hinders is finding the global formula :

OP = discount amount × 100 / discount %
