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 accounts reaches $220?

A)6w + 100 = 220
B)6w - 100 = 220
C)6w + 220 = 100
D)6 + w = 220

Answer 1

A is right because the 100 stays the same since you start out with it and you add the 6 multiplied by x depending on the number of weeks it takes to reach 220.
