Answer:
Company A makes more for one purchase, and Company B makes more for ten purchases. Company C makes less for one purchase and Company A makes less for ten purchases.
Step-by-step explanation:
Company A: y = -3/5x + 65
Company B: y=1/2x + 62
Company C: 11/25x + 57
Make sure x is 1 then do all the equations, then x is 10 and do all the equations to see which has more amount of money and which has less.
Company A: 64.4 (if x = 1)
Company B: 62.5 (if x = 1)
Company C: 57.44 (if x = 1)
<em>if x = 10</em>
Company A: 59
Company B: 67
Company C: 61.4
(I might be wrong since I'm 14)
Company A makes more for one purchase, and Company B makes more for ten purchases. Company C makes less for one purchase and Company A makes less for ten purchases.

-2(x -2y) +(2x +y) = -2(-1) +(3) . . . . -2 times [eq2] + [eq1]
-2x +4y +2x +y = 2 +3 . . . . eliminate parentheses
5y = 5 . . . . . . . . collect terms
