Abusiness can rent a photocopy machine and pay either $70/week rental plus $0.02 per copy or $45/week and $0.04 per copy. up to what number of photocopies can be made so that the second option will be the equivalent or better choice?

Basically we just use this inequality:

70 + 0.02x = 45 + 0.04x

25 + 0.02x = 0.04x

25 = 0.02x

x = 1250

It will be the better choice if you make 1250 copies or less

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
