The call first cell phone company charges 535 per month and an additional 50.16 for each text message sent during the month. another cell phone company, cellular plus, charges $45 per month and an additional $0.08 for each text message sent during the month a. how many text messages would have to be sent in a month to make both plans cost the same?

(The problem doesn't have solution as stated, i think you press 5 instead of $ on 535 and 50.16. With this as initial prices, they would never cost the same.)

Step-by-step explanation:

We can express the charge c of the Call First company as:

where m is the number of messages sent.

For Cellular plus

.

Now, for a number of messages m' the cost will be the same

Now, we can work the equation a little

So the number of messages that needs to be sent have make both plans cost the same is 125.

12

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
