请帮做一道数学题

Of the following, whish is the greatest amount of money that a
person can borrow at an annual interest rate of 6.5 per cent if the loan and
interest are to be paid off at the end of one year with the money from a
check of $. 1,600?
(A) 2,460 (B) 1,704 (C) . 1,520 (D) 1,500
(E) 1,040

Answer 1

As the loan and the interest to be paid at the end of one year, let the loan be x
what we need to pay is x+6.5%x which should be equals or less than $1,600
therefore 1.065x<=1600
x is less or equal to about 1502.
So we choose D.
But you can also choose E because the bank will be very happy to receive more money~~:-)

Answer 2

b

Answer 3

By the end of 1 year, the person have to pay 1+6.5% = 1.065 of what he originally borrowed. This can't exceed 1600, so the greatest amount he can borrow is 1600÷1.065 ≈ 1502.35.
So (d) would be the closest answer.
