Tammy has $20 to spend at the movie theater. She spends $9.50 on a movie ticket. If the snack counter sells bags of candy for $3.50 each, how many bags of candy can Tammy buy with the money she has left?

PLEASE EXPLAIN

WRONG QUESTION, QUESTION I MEANT TO COPY AND PASTE:

Becky is buying fabric to make new pillows for her couch. She spends $71.50 on striped fabric and $52.25 on checkered fabric. If both fabrics cost $5.50 per yard, how many total yards of fabric does she buy?
Write your answer as a whole number or decimal.

What don't you get? Just write down the facts!

71.50/5.50 = 13 yds striped
52.25/5.50 = 9.5 yds checked
so she got 13 + 9.5 = 22.5 yards of fabric
