4. $10,000 is deposited in a savings account earning 1.75% simple interest.
What is the future value (nearest penny) of the $10,000 after 5 years?
What is the future value after 5 years if the same account earns 1.75% interest compounded annually?
You borrow $2000 on March 20 at 15% simple interest.
a. How much interest (to the nearest penny) accrues by September 20 (180 days later). Assume ordinary interest.
b. What is the total amount that you must repay?
A car has an advertised price of $22,000 cash or $650 per month for 4 years. If you pay the $650 per month for 4 years, what is the total amount you would be paying for the car?
If I = Prt and I = $398.90, r = 9.85% and t = 1 year, how much is P (to the nearest dollar)?
If a loan is held for 180 days, then t is about: A. 180 B. 1/2 C. 1/4 D. 3
Please show work. Thank you.
4.
Future value = P (1+ rt)
P = Principal = $ 10,000
r = Rate of interest = 1.75 % or 0.0175 p.a.
t = Time in years = 5 years
Future value = $ 10,000 x (1+ 0.0175 x 5)
= $ 10,000 x (1+ 0.0875)
= $ 10,000 x (1.0875)
= $ 10,875.00
Future value of $ 10,000 using simple interest after 5 years is $ 10,875.00
Future value = P x (1+ r) t
Future value = $ 10,000 x (1+ 0.0175) 5
= $ 10,000 x (1.0175) 5
= $ 10,000 x 1.09061656433662
= $ 10,906.1656433662 or $ 10,906.17
Future value of $ 10,000 using compound interest after 5 years is $ 10,906.17
a.
Ordinary interest = P x r x t
P = Principal = $ 2,000
r = Rate of interest = 15 % or 0.015 p.a.
t = Time in years = 180/365 years
Ordinary interest = $ 2,000 x 0.015 x 180/365
= $ 2,000 x 0.015 x 0.493150684931507
= $ 147.945205479452 or $ 147.95
b.
Total amount to pay = Principal + Interest = $ 2,000 + $ 147.95 = $ 2,147.95
-----------------------
Total amount to pay for the car = EMI amount x Number of EMI
= $ 650 x 4 years x 12 months
= $ 31,200
--------------------------
I = P x r x t
P = I/ (r x t)
= $ 398.90/ (0.0985 x 1)
= $ 398.90/0.0985 = $ 4,049.7461928934 or $ 4,049.75
-------------------------------
180 = 180/360 = 0.5 or ½ years
Time in years, t is about ½ years
