A computer is worth $4000 when it is new. After each year it is worth half what it was the previous year. What will its worth be after 4 years? Round your answer to the nearest dollar.

$250

Step-by-step explanation:

The computer reduces by half of its value every year. It is originally valued at $4,000 so the value in 4 years can be calculated by the formula:

= 4,000 * 0.5 ^ number of years

= 4,000 * 0.5⁴

= $250

Another method is to reduce by half every year:

First year = 4,000 / 2 = $2,000

Second year = 2,000 / 2 = $1,000

Third year = 1,000 / 2 = $500

Fourth year = 500 / 2 = $250

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the answer is: the length is 5/6 yards.
