These are the two phone companies
Talks-A-lot: y = 40 + .35x

Chat-away: y = 50 + .10x

x= 40, y = 54

If you plan to talk to 1000 minutes, which company should you hire?

Please tell me how you got this answer. Thank you

X represents minutes right?

anonymous · Answer

yes, y is the total cost and x represents the number of minutes

anonymous · Answer

Alright, in each one plug 1000 in for x, and see which one of the total cost is less

anonymous · Answer

I solved most of it until that last question. I'm stuck on it :/

anonymous · Answer

Oh, that's all I have to do?

anonymous · Answer

& do I still use 54 for y?

anonymous · Answer

No you just plug in  1000 for x and solve

y=40+.35(1000)
y=?

anonymous · Answer

y = 390

anonymous · Answer

Right, now do the same for the second one

anonymous · Answer

y = 150 correct?

anonymous · Answer

Right, so the second one is cheaper
