Problema Solution
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?
Answer provided by our tutors
let x represent the number of help sessions this year, x >0, x is integer
25.50 + 10.50x <= 70
by solving we find:
x <= 4.24

since we need the greatest integer that is smaller that 4.24 follows x = 4 help sessions.
the maximum number of help sessions that John can use this year is 4.
