Question

1. a couch normally costs $630 but was on sale for $575. what was the percent discount?

Explanation:

Step1: Find the amount of discount

$630 - 575=55$

Step2: Calculate the percent - discount

The percent - discount formula is $\frac{\text{Discount amount}}{\text{Original price}}\times100\%$. So, $\frac{55}{630}\times100\%=\frac{5500}{630}\approx8.73\%$

Answer:

Approximately $8.73\%$
