Find the amount and present value of 10 quarterly payments of $ 1500, if the interest rate is 25% compounded each month.
BlackZzzverrR [31]

Given Information:

Monthly payment = MP = $1500/4 = $375

Monthly interest rate = r = 25/12 = 2.083%

Required Information:

Present Value = ?

Answer:

PV = \$10,110

Explanation:

n = 10*4

n = 40 monthly payments

The present value is found by

$ PV = MP \times  \frac{ (1 - \frac{1}{(1+r)^n} )}{r}  $

Where r is monthly interest rate.

MP is the monthly payment.

$ PV = 375 \times  \frac{ (1 - \frac{1}{(1+0.02083)^{40}} )}{0.02083}  $

PV = 375 \times (26.96)

PV = \$10,110

Therefore, $10,110 is the present value of 10 quarterly payments of $1500 each at 25% interest rate compounded each month.

What's 90 increased by 60%
lozanna [386]

Answer:

144 <em>is the increased number.</em>

Step-by-step explanation:

<em>The first step would be to turn the percentage into a decimal. To do that, divide it by 100.</em>

60 / 100 = .6

Then, multiply that by 90.

.6 * 90 = 54

Add both together to get the increased price.

90+ 54 = 144

<em>:)</em>
