Answer:
$2686.27.
Step-by-step explanation:
The formula for the amount of money after compound interest is
where P is the principal, r is the rate, n is the number of times the interest is compounded per year, and t is the number of years. $1500 is the principal amount of money. 6% in decimal form is 0.06 (divided by 100), so the rate is 0.06. The interest is compounded once per year, so n = 1. And it's after 10 years, so t = 10. So now we can substitute:
Answer:
a. D'(p) = -10p - 6
b. There is a decrease of 96 units of demand for each dollar increase
Step-by-step explanation:
The demand function is:
(a) The derivate of the demand function with respect to price gives us the rate of change of demand:
(b) When p = $9, the rate of change of demand is:
This means that, when p = $9, there is a decrease of 96 units of demand for each dollar increase.
