Rose’s checking account has a balance of -$54. she makes no more withdrawals but deposits $15 per day in her account over the next 5 days. on the sixth day, she makes no deposits, but the bank charges a maintenance fee of $5. what is the balance in her account on the sixth day?

16

Step-by-step explanation:

I know the answer is 16 because i took the the test

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
