Question

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

minutes =x
24 + 0.06x Plan A
30+0.05x Plan B
so both cost same...
24+0.06x = 30 +0.05x
solve for x

Answer 2

120

Answer 3

explain

Answer 4

Set up an expression for each plan, then set the expressions equal.
Let m = number of minutes.
Cell Plus: Fixed $24 + $0.06/minute
24 + 0.06m

Cell Best: Fixed $30 + $0.05/minute
30 + 0.05m

Solve the equation for m:
24 + 0.06m = 30 + 0.05m

Answer 5

and it would all add up to 300 right ?

Answer 6

the answer was 300. thanks for the help -_-

Answer 7

24 + 0.06m = 30 + 0.05m
- 0.05m - 0.05m
-----------------------
24 + 0.01m = 30
-24 -24
------------------
0.01m = 6
Divide both sides by 0.01
m = 600
It takes 600 minutes for both plans to cost the same.
