GREYUIT [131]

Answer:

The answer is approx 75 months.

Step-by-step explanation:

We have P = 3000

r = 14%

Monthly payment = $60

We will use the formula :

[(0.14/12) \times3000] / [1- (1+(0.14/12)^{-12n}]

Solving this we get n = approx 75 months. After 75 months few dollars will be left. And in the 76th month the balance will become negative.

For easy and better understanding, I have attached an excel sheet.

The answer is approx 75 months.

What is the width of a rectangle with a length of 12cm and area of 192cm2
vagabundo [1.1K]
Area = Length x Width

192 = 12 x width

192 = 12width
 
width = 192 ÷ 12

width = 16 cm
