When John bought his new computer, he purchased an online computer help program. The help program has a yearly fee of $25.50 and a $10.50 charge for each help session a person uses. If John can only spend $170 for the computer help this year, what is the maximum number of help sessions he can use this year?

Question

perl · Answer

Let x = # of help sessions

25.50 + 10.50*x  <= 170

chaise · Answer

This question can be set up like a linear equation, in the form of:

$$y=mx+b$$

Where: 
y is the amount John can spend on his computer help
b is the yearly fee (in this case the start up cost, when x=0
m is the charge for each help session
x is the amount of times he uses the help session. 

Do you think you can work it out from here, or do you need more help?
