In your equation: a+(-4)=-13
you then add four to each side,

so a= -9
You would start by saying his budget is $80 so you start with 80= he pays an initial fee of $59.50 every month plus $5 per gigabyte so you would set it up like
80=59.50+5x
X being how many gigabytes he uses then you solve 80-59.50 is 20.5 divided by 5 gives you 4.1 but you round down cause you don’t want to pass the limit so therefor the most gigabytes he can use is 4
the difference from 40000 to the future value in 2020, namely 5 years later is simply the yield or interest amount.
