Answer:
<h2>Caitlin bought 6 cd's.</h2>
Step-by-step explanation:
Givens:
- Caitlin has a $10 giftcard.
- The cd's she wants cost $7 per unit.
- All cd's she picked cost $32.
Basically, to answer this question, we have to find the total number of cd's that she bought in such way that after the discount, she pays only $32.
If we think about, 6 cd's cost 6(7)=42, that is, $42, now with the $10 discount, she would pay only $32, which is the final price shown in the problem.
Therefore, Caitlin bought 6 cd's.
