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 bill?
A. 0.050
B. 0.950
C. C-0.05
D. C+0.95
​

Answer 1

0.95c

100% minus 5% is 95%, or 0.95. This means Sally only has to pay 0.95 times the grocery bill, or c, which represents 0.95c.
