Each week Marissa withdraws the same amount from her bank account. The equation

\[A = 1550 - 90w\]

represents the relationship between the amount of money remaining in her account \((A)\) in dollars, and the number of weeks of withdrawals \((w)\).

For how many weeks has Marissa made withdrawals when the amount remaining in the account is $110?

A. 14
B. 16
C. 17
D. 18

Answer (2)

Fill in your remaining amount (110) in a because a is your remaining amount.
Solve for w(weeks):
110=1550-90w Subtract 1550 on both sides of the equal sign to get:
-1440=-90w Now do the inverse operation and divide -90 on both sides to get:
16= w
So the answer is 16 weeks
