Question
1.The cost of a telephone call from Wilsonto East Meadow is $0,60 for the first three minutes plus $0.17 for each additional minute. What is the greatest number of whole minutes of a call if the cost cannot exceed $2.50?
2.When John bought his new computer, he purchased an online computer help service. The help service 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?
PLEASE HELP!!!

1. Suppose a person only uses the first 3 minutes repeatedly. Then 4 minutes max. But they also state 0.17 for every additional minute, which is cheaper. We can use an equation to solve for how many minutes a person can make the call. Let x be the number of minutes.
0.60+0.17x <= 2.50
0.17x <= 1.90
x <= 11.17 minutes, but since it says "whole minutes", we round down to 11. However, remember that 0.60 is for THREE minutes. So total call time was 11+3 = 14 minutes as the greatest number of minutes for a call.

2. Same idea as above, just different numbers.
25.50 + 10.50x <= 170
10.5x <= 144.5
x <= 13.76
But since you can't have "0.76 of a help session", it would be 13 full help sessions he can use this year.
