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.
