Answer 1

Taylor bought 5 dozen oranges. One dozen equals 12, so:

\[
5 \text{ dozen} = 5 \times 12 = 60 \text{ oranges}
\]

Next, we need to calculate how many oranges were used to make juice and how many were given to his daughter.

**Step 1: Calculate 30% of the oranges used for juice:**

\[
30\% \text{ of } 60 = 0.30 \times 60 = 18 \text{ oranges}
\]

**Step 2: Calculate 15% of the oranges given to his daughter:**

\[
15\% \text{ of } 60 = 0.15 \times 60 = 9 \text{ oranges}
\]

**Step 3: Calculate the total number of oranges used:**

Total oranges used = oranges for juice + oranges given to daughter

\[
18 + 9 = 27 \text{ oranges}
\]

**Step 4: Calculate the number of oranges left:**

\[
60 \text{ oranges} - 27 \text{ oranges} = 33 \text{ oranges}
\]

So, the number of oranges Taylor had left is:

\[
\boxed{33}
\]
