Answer:
B) $6.60
Step-by-step explanation:
First, we need to calculate the tax, so we need to find 7% of $12.52 as follows:
![12.52*7\text{ \% = 12.52}*(7)/(100)=0.8764](https://img.qammunity.org/2023/formulas/mathematics/college/z3r6q44a4plymywdsmksmhp13daarmwx2t.png)
Now, Brian will pay $12.52 plus $0.8764 for the tax, so he will pay in total:
$12.52 + $0.8764 = $13.3964
Finally, If he pays with a $20 bill, he should receive:
$20 - $13.3964 = $6.6036
Therefore, the answer is B) $6.60
