Question

John starts a saving account with $100. Every week he adds $6 to his account. Which equation can be used to determine the number of weeks, w, after which John's account reaches $220?
A: 6w + 100 = 220
B: 6w - 100 = 220
C: 6w + 220 = 100
D: 6 + w = 220

Answer 1

A would be your answer. If we did 220-100 and divide that by 6, you'd get the equivalent of w.
