Question

Which inequality can be used to determine how many T-shirts Christopher can buy?

a. 4.99+8.5n≥75
b. 8.5n−4.99≤75
c. 4.99−8.5n≥75
d. 8.5n+4.99≤75

Answer 1

The correct inequality that can be used to determine how many T-shirts Christopher can buy is a. 4.99 + 8.5n ≥ 75.

Step-by-step explanation:

The correct inequality that can be used to determine how many T-shirts Christopher can buy is a. 4.99 + 8.5n ≥ 75. This inequality represents Christopher's budget constraint, where the total cost of the T-shirts (represented by 4.99 + 8.5n) must be greater than or equal to 75 dollars. By solving this inequality, we can find the range of values for n (the number of T-shirts Christopher can buy).
