Question

One cell phone plan costs $29.94 per month plus $.10 for MB of data. Another plan costs $32.99 per month
plus $.05 for each MB of data. For how many MBs of data will the monthly bill for be the same for both plans?

Answer 1

Write an equation for both.

Cellphone Plan #1:

y = 29.94 + 0.10x

Cellphone Plan #2:

y = 32.99 + 0.05x

Where x = MB of data.

Answer 2
