Answer:
Formula: Future value of annuity
In 20 years: $249,875
Total Interest: $99,875
Step-by-step explanation:
Use the formula for future value:
FV =
P = $6,000
r = 0.04
n = 1
t = 25
FV =
FV = $249,875
To find the total interest earned, first find the total value of the deposit payments:
$6,000 annual payments for 25 years = 6,000 • 25
= $150,000
(I copied that explanation from somewhere else so its a little messed up. I just couldn't explain it properly. Hope this helps!)
First of all, Jamie's room is really weird. Second of all, let's solve. Since the formula for the area of a circle is (pi)r^2, and Jamie's room is exactly half of that, the area for a semicircle would be (1/2)(pi)r^2. The straight wall is the diameter, so half of the diameter would be the radius. Half of 14 is 7. Now, you rewrite the equation and substitute the values of the variables. The new equation (if you're using 3.14 for pi) is (1/2)(3.14)(7^2), or (1/2)(3.14)(49). From here you can solve, so the answer would be 76.93. Jamie needs 76.93 square feet of carpet.
