Answer:
$755.80
Step-by-step explanation:
Determine the compound amount first and then subtract the principal from it, to find the amount of interest.
The compound amount formula is A = P (1 + r/n)^(nt), where
P is the initial principal, r is the interest rate as a decimal fraction, n is the number of compounding periods per year, and t is the number of years. Here, P = $2179; t = 5 yrs; r = 0.06; and n = 4 (quarterly compounding).
We get:
A = $2179(1 + 0.06/4)^(4*5), or $2179(1.015)^20, or $2179(1.347) = $2937.80.
The compound amount is $2934.80. Subtracting the $2179 principal results in the interest earned: $755.80.
Answer:
2, 19, -3
Step-by-step explanation:
First, you need to know what is 25 percent of 45, so you do 45 times 25 divided by 100 and you are going to get 11.25. Then you take the 45 and subtract those 11.25, which will give you 33.75 because it's saying how much was it before the sale. That's your final answer.
You’ll need to divide 1,644 and 13 since the manager wants to put 1,644 polished rocks into small bags. And 13 rocks is how much will be in each bag. So you’ll do 1,644/ 15 = 109 with 6 left over. Hope it’s correct :)
