Question

Lloyd currently has $80 in his bank account and he earns $130 a week at his current job. Write a function, S, that represents the amount of money Lloyd has in his account after w weeks

Answer 1

Let's call the number of weeks passed w.

Then each week his money goes up by $130. Then, we can write this as:

`130w`

But, he has an additional $80 dollars, then to the money he earns each week we need to add this quantity

`S(w)=130w+80`

This is the function asked in the problem.
