To estimate the cost of each T-shirt, we should divide the total amount spent by the number of T-shirts.
Roberto spent $49.62 for 6 T-shirts, so we want to estimate \( 49.62 \div 6 \).
Looking at the given options:
A) \( 45 \div 5 = 9 \) - This does not represent the correct number of T-shirts or the total cost.
B) \( 48 \div 6 = 8 \) - This is a close estimate of \( 49.62 \div 6 \) since it uses 48 as an approximation for 49.62 and uses the correct number of T-shirts.
C) \( 50 \div 10 = 5 \) - This does not reflect the actual number of T-shirts correctly and gives a poor estimate.
D) \( 50 \div 5 = 10 \) - This also does not reflect the actual number of T-shirts correctly and gives a poor estimate.
Given the approximations and the correct number of T-shirts, the best choice is:
**B) \( 48 \div 6 = 8 \)**.
