Answer 1

Answer:

C ) 20%

Step-by-step 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

$\frac{Amount (part)}{Base (whole)} = \frac{Percent}{100}$

*now plug in the numbers*

1.   $\frac{3.50}{16.50} =\frac{X}{100}$

2.  $\frac{3.50}{1} *\frac{3.50}{16.50} =\frac{X}{100}*\frac{1}{3.50}$

3.  $16.50 =\frac{X}{350}$

4.  $350/16.50 =\frac{X}{350}/350$

     $350/16.50 =X$

5.   21.21 = X    

round to the nearest whole number which would be

20%
