Problema Solution
Farzana has a prepaid cellphone that costs $1 per day plus $.10 per minutes she uses. She has a daily budget of $5 for phone costs.
Answer provided by our tutors
we assume the goal is to solve for the number of minutes per day Farzana can call and stay within a $5 daily budget
let 'm' represent the number of phone call minutes
5 >= 0.10m + 1
4 >= 0.1m
m <= 4/.1
m <= 40
Farzana can call up to 40 minutes per day and stay within a $5 daily budget
