Answer 4

you sure?

Answer 5

Apologies for the incorrect response earlier. Let's find the correct slope now.

To find the slope, we can use the formula:

slope = (change in y)/(change in x)

Considering the given information:

The total cost for ordering five uniforms is $66, and the total cost for ordering eight uniforms is $101.

Change in y = $101 - $66 = $35
Change in x = 8 - 5 = 3

slope = (35/3)

Hence, the correct answer is:

A. The slope is 35/3.
