Answer:

Caitlin had bought 6 CD's for herself.

Step-by-step explanation:

We know that:

  • 1 CD = $7
  • Cost of CD's: $10 + 32

Since she had $10 gift certificate and used it in the $7 bargain bin, we know that 32 + 10 must've been her real cost without crediting the gift card. When we divide the real cost by 7, we get the number of CD's bought by Caitlin.

Work:

  • 32 + 10 = 42

This means that the real cost was $42.

  • 42 ÷ 7 = 6

Hence, Caitlin had bought 6 CD's for herself.

Hoped this helped.
