Question

a store manager is marking down microscopes from $275 to $77. what is the discount percentage? write your answer using a percent sign (%).

Explanation:

Step1: Find the discount amount

First, we need to find the amount of the discount. The original price is $275 and the new price is $77. The discount amount is the original price minus the new price.
$275 - 77 = 198$

Step2: Calculate the discount percentage

The discount percentage is calculated by dividing the discount amount by the original price and then multiplying by 100 to get the percentage.
$\text{Discount Percentage} = \frac{198}{275} \times 100$
First, calculate $\frac{198}{275} = 0.72$
Then, $0.72 \times 100 = 72\%$

Answer:

72%
