Question

Justin bought a computer monitor on sale for 35% off the original price, m. He spent $130 on the monitor. What was the original price (m)?

Answer 1

$200

Explanation:

The original price is unknown, so we let m = original price.

The original price was 100% of the original price since 1005 of something is the entire thing.

The discount was 35%. 100% - 35% = 65%.

When you subtract 35% from 100%, you get 65%, so after taking off the 35% discount, the amount that was paid was 65% of the original price.

65% of m = $130

0.65m = 130

m = 130/0.65

m = 200

Answer: $200
