I need help with this question please

Write an equation and solve. One telephone company charges $16.95 per month and $0.05 per minute for local calls. Another company charges $22.95 per month and $0.02 per minute for local calls. For what number of minutes of local calls per month is the cost of the plans the same?

Answer 1

200 minutes

Explanation:

First you need to make two equations for the rates of each telephone company

The first equation will be y = 0.05x +16.95 and the second equation will be

y = 0.02x + 22.95

Then you need to set the two equations equal to each other in order to find where the number of minutes of local calls per month is the same

Answer 2

200 minutes

Explanation:

16.95 + 0.05 x = 22.95 + 0.02 x

0.05 x - 0.02 x = 22.95 - 16.95

0.03 x = 6.00

x = 6.00 / 0.03 = 600 / 3 = 200
