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
anastassius [24]

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!!

How do you simplify, explain<br> -3√7 -3√7 -2√32
andreev551 [17]
Since the first two numbers have the same radical, they can be combined. 
-3√7-3√7=-6<span>√7
Simplify -2</span>√32 to get -8<span>√2.

So simplified, you would get -6</span>√7-8<span>√2.</span>

Two column proof 2n-21=n/4
natita [175]

Simplifying:

2n-21=0.25n


We move all terms containing n to the left and all other terms to the right.

+2n-0.25n=+21


We simplify left and right side of the equation.

+1.75n=+21


We divide both sides of the equation by 1.75 to get n.

n=12
