Question

Someone please help with this!

Answer 1

Explanation:

a) At time 0, the value was $1000, so the computer cost $1000.

b) At time = 5 years, the value is zero.

c) In the first year, the value went from $1000 to $800 in 1 year.

It lost $200 of value, so the slope is -200.

It means the computer loses $200 of value per year.

Answer 2

a) $1000

b) 5 years

c) -200; a decrease of $200 in value each year

Explanation:

a)

When the age of the computer is 0 years, the graph shows its value to be $1000.

The original cost of the computer is $1000.

__

b)

The graph shows the value is 0 when time is 5 years.

After 5 years, the computer no longer has value.

__

c)

The value decreases 1000 in 5 years, so does so at the rate of $1000/5 = $200 per year.

The slope is -200. It means the value decreases by $200 each year.
