Question

Elena has $225 in her bank account. She takes out $20 each week for w weeks. After w weeks has d dollars left in her bank account. How much money remains in the account after 7 weeks

Answer 1

85$ left

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!
