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

24*m+.06min=cell plus
30*m +. 05min=cell best

Answer 2

if you make the ms 1 and the mins xs then you have a y=mx+b equation

y=.06x+24
y=.05x+30 now just solve you can view it as plugin in the y into the other.

.06x+24=.05x+30

Answer 3

I don't get it

Answer 4

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.

that can be interpreted as 24*month +.06 minutes=cellplus's prize
---
Cell Best has a plan that costs $30.00 per month plus an additional $0.05 per minute.

that can be interpreted as 30*month+.05*minute= cellbest's prize

How many minutes can Trevor talk and both cell plans cost the same amount?

first we put both math interpratations one on top of the other.
24*month +.06* minutes=cellplus's prize
30*month+.05*minute= cellbest's prize

We assume that in 1 month how many minutes can Trevor talk and both cell plans cost the same amount?

we plug in 1 where the months are at

24*1 +.06* minutes=cellplus's prize
30*1 +.05*minute= cellbest's prize

SInce they ask for when are both prices the same. THe math interpretation is
cellplus's prize=cellbest's prize

We plug in therefore

24*1 +.06* minutes=30*1 +.05*minute

But in the other problem we just uses x's in place of minutes :) and y's in place of prizes. You just solve for minutes.

Answer 5

so its C?

Answer 6

i get 600

Answer 7

.06x+24=.05x+30
.06x=.05x+6 subtract 24 both sides
.01x=6 subtract .05 both sides :)

x=6/.01 which is 600 when you divide.

Answer 8

thank you!
