Question

Sally has a discount card that reduces the price of her grocery bill in a certain grocery store by 5%. If c represents the cost of Sally’s groceries, which expression represents Sally’s grocery bills

Answer 1

Percentage discount = 5%
Percentage price of groceries after discount=100-5=95%
Given that the total price was c, sally's bill will be:
0.95×c
=0.95c
thus the expression is 0.95c
