Question

Can anyone help me please guys?

Answer 1

Cost of the tires in 2008 = 23333 dollars

Explanation:

Number of snow tires purchased are represented by,

T =
`(500(t+20))/((t+75))`

Where t = duration from year 2000

Similarly, cost of the tires area represented by,

C =
`(t+75)/(1-.05t)`

Therefore, cost of T tires = C × T

=
`(t+75)/(1-.05t)` ×
`(500(t+20))/((t+75))`

=
`(500(t+20))/(1-0.05t)`

Now cost of the tires in year 2008 (t = 8 years)

Total cost =
`(500(8+20))/((1-0.05* 8))`

=
`(14000)/(0.6)`

= $23333.3

≈ 23333 dollars
