Question

You can order 2 shirts for $35 from a certain mail order company. From that same company, you can order 4 shirts for $55. You can assume that the price increase is constant depending on the number of shirts ordered.

Answer 1

use the slope formula if the question u asking is what is the slope which is rate of change. (y'-y)/(x'-x)

2 and 4 will be your x
35 and 55 is your why

55-35= 15
4-2= 2
so 15/2 is 7.5, so slope is 7.5
