per month plus a monthly line fee of $30
per phone. The cost of the family plan is $20
per month and her monthly bill is $169.38
. Enter and solve an equation to find how many phones are on the plan.

Answer 1

2 lines @ 30.00

2 phones @ 44.69

1 plan @ 20.00

169.38

Explanation:

20.00 + 44.69x +30.00y = 169.30

169.38- 20 = 149.38 = 44.69(2) + 30.00(2)

169.30- 20.00 = 149.38 = 89.38 + 60.00
