Answer:
A- Multiplication and Addition.
Step-by-step explanation:
Two shirts for $21.99 each, you'd need to use multiplication to find that out.
$45.59 and $21.99 (2x), you'd need to use addition to find out that total.
All you have to do is divide by the same number for both so on this one it's 11 so it's 1/6
