Question

Ted and Mary ordered meals costing a total of $30, including tax. They left an 18% tip. How much did they spend in all?

Answer 1

Answer:

D $35.40

Step-by-step explanation:

We need to find 18% of $30 and then add it to the $30 total.

To find a percent of a number, change the percent to a decimal by moving the decimal point two places to the left. Then multiply it by the number.

18% of $30 =

= 18% * $30

= 0.18 * $30

= $5.40

The tip was $5.40. Now we add the tip to the total.

$30 + $5.40 = $35.40

Answer: D $35.40
