Mary is about to pay for five items at the grocery store. The prices of the items are

\$7.99,

\$4.99,

\$2.99,

\$1.99,

and

\$0.99.

Mary will pay with a twenty-dollar bill. Which of the following is closest to the percentage of the

\$20.00

that she will receive in change?

Show solution

Solution

The prices total

\$18.95,

so the change is

\$1.05.

As a percentage of

\$20.00,

this is

\frac{1.05}{20}\cdot100\% = 5.25\%.

The closest listed percentage is

5\%.

Thus, the correct answer is A.
