Answer:
Store A = 3.4521
Store B = 2.9589
Store C = 4.4384
Explanation:
Store A charges ADB method
purchase made on 5th first payment on 15th of 100
so from 5th to 15th Average daily balance =300 for 10 days
then from 15th to 4th for remaining 20 days average daily balance = 200
Average Daily Balance = (300*10+200*20)/30
Total finance charge = ADB*(APR*(Days/365))
=300*((0.18)*(10/365))+200*((0.18)*(20/365))
= 1.4795+1.9726=3.4521
Store B
Adjusted Balance Method uses adjusted balance to calculate the charges
Adjusted balance=Starting balance adjusted for credit and debit
Adjusted balance =300-100=200
Financial Charges = 200*(.18*(30/365))=2.9589
Store C
Previous Balance Method the interest is calculated on amount of balance carried from previous billing cycle
Balance Carried = 300
Charges =300*(.18*(30/365))= 4.4384
Answer:
X=97.24
Explanation:
PV = Present Value = X+2000 by the 16th years
PMT = Payments = $100
FV = Future Value = 2000 at the end of 16 years
n= number of years
Applying the equation of future value for annuity
FV = pmt* ((1+r)ⁿ - 1
)/r
Inputting the values;
2000=100*((1+r)¹⁶-1)/r
Solving for r, gives r = 2.9%
Therefore using the formula for PV for annuity;
PV=PMT*(1-(1/1+r)/r)
X=100*(1-(1/1.029)/0.029
X=100*((1-0.9718)/0.029)
X=100*(0.0282/0.029)
X=97.24
