An investment yielded an interest payment of $350 each month when the annual interest rate was 9%, what is the amount of the investment that should be invested with an annual interest rate of 8% if
We want to gain 15% more each month?

$60,375
$50,400
$41,300
$32,500
$25,100

Answer(s): A

Explanation:

The new monthly payment should be 1.15 x $350 = $402.5. Now we’ll proceed with the formula: Principal × percent interest = interest earned
Principle × (0.08)× 1/12 = $402.5.
Solve for the principal (402.5 × 12)/.08= $60,375.

QUESTION: 287

An investment gained an interest payment of $250 each month when the annual interest rate was 8%, how much more should we invest annually if we want to gain 12% more per month with a new annual interest rate of 7.5% ?

$9,360
$9,100
$8,250
$7,300
$7,150

Answer(s): D

Explanation:

The new monthly payment should be 1.12 x $250 = $280. Now we’ll proceed with the formula: Principal × percent interest = interest earned
Solve for the principal for the 9% interest: (250 × 12)/.08= $37,500, this is what we invested before.
Solve for the principal for the 6.5% interest: (280 × 12)/.075= $44,800, this is what we should invest with the new interest. (44800 – 37500 = $7,300) is the amount to be added to the prime payment.
