Answer:
<em>Maximum Interest rate R≈0.06167 ≈0.6167 % </em>
Explanation:
Answer:
Explanation:
Let: P be the loan amount(P=$100000), R be rate(R=?), I be interest after 10yrs(I=?), T to be time to repay (t=10yrs 12=12months: <em>since a certain amount is set up on a monthly bases for the purpose of payment, we assume a monthly rate</em>)
To get the interest I paid at the end of 10yrs, do the following:
let total lump sum repayable be TL
∵TL=$1450x12monthsx10yrs=$174000
Hence,
I=$174000-$100000=$74000
Using R=
where I=$74000, P=$100000 and T=10*12=120months
R==0.006167
R≈0.006167
multiplying R by 100, we have R in percentage as,
<em><u>R≈0.6167 % Interest rate</u></em>
