Answer

Answer:

D. $5

Explanation:

Step1: Find the price difference

$175 - 165=10$

Step2: Find the difference in number of shirts

$7 - 6 = 1$

Step3: Calculate the price per shirt

Since the difference in total cost ($10$) is due to the difference of 1 shirt, the cost of one shirt is $\frac{10}{1}=5$.
