Answer:
85$ left
Step-by-step explanation:
You can set up an equation like so:
225 (how much she has to start)
20 (how much she takes out each week)
w (how many weeks she took money out)
d (how much she has remaining)
225-20w=d
Substitute 7 in for w so you can find out how much she has left after 7 weeks:
225-20(7)=d
Then simplify:
225-140=d
85=d
85$ is your answer
Hope this helps!
