The value of a car is decreasing by 14% per year. If the car is worth 11,000 today, what will it be worth in two years?

Xelga [282]

For us to be able to determine the worth of the car in two years, we will be using the depreciation formula:

$\text{ FV = PV(1 - }\frac{r}{100})^n$

Where,

PV = Current value of the car

r = rate of interest

n = number of years

FV = Future value

Given:

PV = 11,000

r = 14%

n = 2 years

We get,

$\text{ FV = PV(1 - }\frac{r}{100})^n$ $\text{= (11,000)(1 - }\frac{14}{100})^2$ $\text{= (11,000)(1 - }0.14)^2$ $\text{= (11,000)(}0.86)^2$ $\text{= (11,000)(}0.7396)$ $=\text{ 8,135.60}$

Therefore, the answer is 8,135.60

Rolls are being prepared to go to grocery stores. Divide 72 rolls into 2 groups so the ratio is 3 to 5.

tekilochka [14]

To do this, nice it to add 3 and 5, then divide 72 by the result of sum 3 and 5. Finally multiply it by 3 and by 5 to get the result.
Lets do this
3+5=8
72:8=9 - number of rolls in 1 "unit"
9*3=27 - first group
9*5=45 - second group
