Solve this problem using a similar strategy.

Yolette charges $12.75 for a manicure and $19.50 for a pedicure. Yolette did 7 manicures and 4 pedicures each day for 5 days. How much money did Yolette earn altogether?

Answer 2

435

Answer 3

Look:

Manicure = $12.75
Pedicure = $19.50
Yolette does 7 Manicures and 4 Pedicures a day.
12.75 x 7 = $89.25
19.50 x 4 = $78.00

89.25 + 78.00 = 167.25.

Since she continues to do this for 5 days, multiply 167.25 by 5.

167.25 x 5 = 836.25

So Yolette makes $836.25

Answer 4

Here's a table:

Number of days: 1 2 3 4 5
Money Earned: $167.25 $334.50 501.75 $669 $836.25

The equation to your graph is 167.25x, where x is the number of days. Just plug in the number of days for x.
