Answer:

$16,748

Step-by-step explanation:

we know that

The equation of a exponential decay function is equal to

$y=a(1-r)^x$

where

y is the value of the car

x is the number of years

a is the initial value

r is the rate of change

In this problem we have

$a=\$25,000\\r=12.5\%=12.5/100=0.125$

substitute

$y=25,000(1-0.125)^x$

$y=25,000(0.875)^x$

For x=3 years

substitute

$y=25,000(0.875)^3=\$16,748$

CAN SOMEONE PLEASE HELP ME WITH THIS QUESTION???

tangare [24]

Answer:

The complete answer is explained below.

Step-by-step explanation:

The problem is demanding to simply determine the number of years each color light would last.

We know the following information from the question:

As it is clear that a red light remains TURNED ON 50% of the time.
Green remains TURNED ON 42% of the time
Yellow remains TURNED ON 8% of the time.

Also the bulbs for each color are LED and are designed to last 100,000 hours. So, each light does last 100,000 hours.

lets make conversions

$1\:day\:=\:24\:hours$

$1\:year\:=\:365\:days$

Dividing $100,000$ hours by $24$ hours would bring $4166.67$ days

Dividing $4166.67$ days by $365$ days would bring $11.4$ years, meaning 11 years and 4 months.
