Question

Okay, confusing word problem... Help anyone?

Trevor's dad decided to get him a cell phone for his birthday. Cell Plus has a plan that costs $24.00 per month plus an additional $0.06 per minute. Cell Best has a plan that costs $30.00 per month plus an additional $0.05 per minute. How many minutes can Trevor talk and both cell plans cost the same amount?

600
60
300
120

Answer 1

This is two linear equations that need to be solved simultaneously.

Equation 1: 0.06t + 24
Equation 2: 0.05t + 30

In both cases, t ins the number of minutes talked for the month.

If you set these equal to each other and solve for t, this will tell you when the two plans cost the same.

Answer 2

Another way to look at is is to say that the base cost for Cell Best is $6 more but you save a penny per minute. So how many minutes would you need to talk to have that extra penny per minute equal $6?

Answer 3

Okay, thanks!
