Calculate the balance of your account after 15 years. Round your answer to the nearest hundredth.

$13,054.13

Step-by-step explanation:

You are going to want to use the continuous compound interest formula, which is shown below.

A = total

P = principal amount

r = interest rate (decimal)

t = time (years)

First, lets change 7.25% into a decimal:

7.25% -> -> 0.0725

Now, plug the values into the equation:

Your balance will be $13,054.13

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
