Answer
You received \$29 in change.
Solution
1. Calculate the total cost of the CDs:
\[
9 \times 2 = 18
\]
So, the CDs cost \$18.
2. Calculate the total cost of the DVDs:
\[
5 \times 4 = 20
\]
So, the DVDs cost \$20.
3. The cost of the iPad is:
\[
33
\]
So, the iPad costs \$33.
4. Find the total amount spent by adding all costs:
\[
18 + 20 + 33 = 71
\]
So, the total cost is \$71.
5. Determine the change received by subtracting the total cost from \$100:
\[
100 - 71 = 29
\]
So, the change you get back is \$29.

First, let's calculate the total cost of the CDs. You bought 9 CDs for \( \$ 2 \) each, which amounts to \( 9 \times 2 = \$ 18 \). Next, the total cost of the DVDs is \( 5 \times 4 = \$ 20 \). Finally, the old iPad cost \( \$ 33 \). Adding all these together: Total cost = \( 18 + 20 + 33 = \$ 71 \). Now, if you paid with a \( \$ 100 \) bill, your change would be: Change = \( 100 - 71 = \$ 29 \). So, you got back about \( \$ 29 \) in change!
