question 11. answer: 22554.45
Step-by-step explanation:
Since we are given a function to use to find the cost of the car, we first need to find the difference in the years 2017 and 2010
2017 - 2010 = 7
So our value for t will be 7.
We can use the formula because it still falls under the expected increase within the 10 year range.
So now let's substitute t in the function.
So it will cost the company $22554.45 to build the car in 2017.
10. answer:
$28,611.75
question 9.
Answer: 12,503 people
Step-by-step explanation:
This is an exponential decrease so to find the population in 8 years you have to use a future value formula:
= Amount * (1 + rate) ^ number of years
= 15,000 ( 1 + (-2.25%)) ⁸
= 15,000 * (1 - 2.25%)⁸
= 12,503.32
= 12,503 people
