Initially invested $800 @ interest rate of 9%. how many years before the investment doubles?

to solve this problem, you need to use this formula:

A=P(1+r/n)n⋅t

 A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

but to save you time, it takes you 8 years and 16 days

366

step-by-step explanation:

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
