Answer:
5 years
Step-by-step explanation:
We are given;
- Initial value of the car = $12,500
- Rate of Depreciation = 13% per year
- New value (after depreciation) = $6,250 (half the initial value)
We are required to determine the time taken for the value of the car to depreciate to half the original value.
- We need to know the depreciation formula;
- New value = Initial value ( 1 - r/100)^n
Therefore;
$6,250 = $12,500(1 - r/100)^n
0.5 = (1 - 13/100)^n
0.5 = 0.87^n
Introducing log on both sides;
log 0.5 = n log 0.87
Therefore;
n = log 0.5 ÷ log 0.87
= 4.977
= 5 years
Therefore, it takes 5 years for the value of the car to depreciate to half the initial value.
The surface area of the teepee is 399.12 square feet
Answer:
I believe it would be 50
Step-by-step explanation:
If those 3 hours are included in those 12 to get there, then you'd want to subtract that to get your actual time spent driving. That would leave you with 9. Then, you'd divide that by 450 to get your answer. (This is if those 3 hours are included in that 12 hour time frame.)
