Question

Please help!!! A phone company offers two long-distance plans. The first charges a flat value of $5.00 per month plus $0.99 for each minute used, and the second charges $10.00 a month plus $0.79 for each minute used.

If x represents the number of minutes used each month, which system of equations represents the total amount of money, y, you would spend for each long-distance plan?

Answer 1

C

Explanation:

Given y = amount of money spend for the long distance plan per month

and x = minutes used each month

Note these 2 plans are in per month basis.

Plan A: Flat $5 + $0.99 Per min used (variable cost)

transform into an equation:

y = 0.99x + 5

Plan B: Flat $10 + $0.79 per min used (variable cost)

transform into equation:

y = 0.79x + 10

Put these 2 equations together, will give you the answer as C.
