Averie · Answer 1

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
