Final answer:
Mr. Gonzales can buy a maximum of 3 bracelets.
Step-by-step explanation:
To determine the maximum number of bracelets Mr. Gonzales could buy, we need to find the amount of money he has remaining after buying a shirt. Mr. Gonzales has $42.50 in total and spent $29 on the shirt.
Therefore, he has $42.50 - $29 = $13.50 left.
Now, we need to find the number of bracelets Mr. Gonzales can buy with $13.50.
Each bracelet costs $4.50, so we divide the remaining amount of money by the cost of one bracelet:
$13.50 ÷ $4.50 = 3.
Therefore, Mr. Gonzales can buy a maximum of 3 bracelets.
