Question

Answer 1

C ) 20%

Explanation:

A. First you have to find out how much change Cindy would have after paying the total bill

$20.00 - $16.50

= $3.50

B. Then you could use proportions to solve percent problems

`(Amount (part))/(Base (whole)) = (Percent)/(100)`

*now plug in the numbers*

1.
`(3.50)/(16.50) =(X)/(100)`

2.
`(3.50)/(1) *(3.50)/(16.50) =(X)/(100)*(1)/(3.50)`

3.
`16.50 =(X)/(350)`

4.
`350/16.50 =(X)/(350)/350`

`350/16.50 =X`

5. 21.21 = X

round to the nearest whole number which would be

20%
