A company paid $140 comma 000140,000 for a new 18-wheeler. When it is 99 years old it will be worth $41 comma 00041,000. Using straight-line depreciation, the value of the truck in dollars, V, is a linear function of its age in years, n. Find the function and the value when the truck is 88 years old.

The cost of truck when the truck is 8 years old is $60,000

Step-by-step explanation:

We are given the following in the question:

Cost of new truck = $140,000

Cost of truck when 9 years old = $41,000

The depreciation is given by the slope of line:

Depreciation value = 10000

The value of truck is given by:

Putting values, we get:

Value of truck at 8 years old:

Thus, the cost of truck when the truck is 8 years old is $60,000
