Question

Please help me with this problem ​

Answer 1

Explanation:

Part A

Cost Mail Order = 0.15x + 2.70

Cost Local = 0.25x

Part B

0.25x = 0.15x + 2.70 Subtract 0.15 from both sides

0.25x-0.15x = 0.15x-0.15x + 2.70

0.1x = 2.70 Divide by 0.1

0.1x/0.1 = 2.7/0.1

x = 27

Part C

Use the local store under 27

Use either if 27 need to be developed

Use the Mail order if the number is greater than 27
