Answer:
In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10
Step-by-step explanation:
90 * x - 90 * 12 = 90(x - 12)
From the question, x = 10
Hence,
90(10 - 12)
(90* 10) - (90 * 12) - - - > correct evaluation
900 - 1080
= - 180
Hence, both values in the bracket, that is 10 and - 12 should be multiplied by 90. Not just 10 alone.
Answer:
No, he is wrong.
Step-by-step explanation:
Since, the total payment of a loan after t years,
Where,
P = present value of the loan,
r = rate per period ,
n = number of periods,
Given,
P = $165,000,
In loan 1 :
r = 3% = 0.03, t = 15 years,
So, the total payment of the loan is,
In loan 2 :
r = 4% = 0.04, t = 30 years,
So, the total payment of the loan is,
Since,
Hence, total amount repaid over the loan will be less for Loan 1.
That is, the friend is wrong.
