Answer: $41.25
Step-by-step explanation: To calculate the sale price, we first need to calculate the discount. The formula for finding the discount is as followed.
Original price × rate of discount = discount
In this problem, the original price is $55 and the rate of discount is 25% off or .25 as a decimal. Now, we have to multiply these two numbers together and we we will get the discount.
55 × .25 = 13.75
The discount is $13.75.
Now, we can find the sale price. The formula for sale price is shown below.
Original price - discount = sale price
The original price is $55 and the discount is $13.75. Now, we have to subtract.
$55 - $13.75 = $41.25
Therefore, the sale price is $41.25.
