Molly opened a bank account. she deposited $86.50 into her account every month for 20 months. she used $24.50 every month to pay for singing lessons. after 20 months, she used 1 over 4 of the total money left in her account to go to a summer camp for singers. what is the total amount of money molly spent to go to the summer camp?

She spent $310 on the singing camp.

MY WORK:

I multiplied $86.50*20 because $86.50 is the amount she deposited for 20 months. $86.50*20=$1740.00

Then I multiplied $24.50*20 because she spent $24.50 for 20 months. $24.50*20= $490.00

Then I subtracted $1740.00-$490.00 because she spent $490 out of her bank account. $1740.00-$490.00=$1240.00

Finally, because its 1/4 of her money, I divided $1240.00 by 4. $1240 divided by 4= $310

Hope this helps!!
