John delivers newspapers he makes $5 the first week and $2 are added to his pay each week he delivers papers. Which expression could be used to find out how much he would make in a given week, w, after the first week?

Question

a) 2w+5
b) 2(w-2)+5
c) 2(w-1)+5
d) 5w-2

Answer 1

you know it's going to involve a +2w somewhere, because he gets $2 more each week.

So, that only leaves A as the logical choice, and it fits because he starts out with 5, and for each w gets 2 more.
