Answer:

She had 72 bracelets, or 6 dozen bracelets.

Step-by-step explanation:

3 1/4 dozen = 3.25 × 12 = 39

2 dozen = 24

3/4 dozen = 9

1 1/2 dozen = 18

She started with x number of bracelets.

She sold 18 in the morning. Now she has x - 18.

She made 9 before the afternoon. Now she has x - 18 + 9.

She sold 24 in the afternoon. Now she has x - 18 + 9 - 24.

After all the activity, she ended up with 39 bracelets.

x - 24 + 9 - 18 = 39

x = 72

Answer: She had 72 bracelets, or 6 dozen bracelets.
