Answer:
The total compound interest is $3,488.50, I hope I helped explain how to find total compound interest
Step-by-step explanation:
So the formula for this would be:
A = P(1+r/n)^nt
A = the amount of your principal plus interest, which is the total
P = stands for the principal, which is your original amount invested
r = shows the interest rate in decimal form
n = stands for the number of compounding periods
So to solve for the compound interest we would plug in our numbers in replacement for the letters
Answer: She has 76 dimes and 78 quarters.
Step-by-step explanation:
Given data:
Total = $27.20
Solution:
Q = d + 2
Each quarter is 25 cents, or 0.25 of a dollar = 0.25q
Each dime is 10 cents = 0.10d
0.25q+0.10d = $27.20
Where q = d-2
Substitute in this equation:
0.25(d+2)+0.10d = 27.20
0.25d + 0.5 + 0.10d = 27.20
0.35d = 26.7
Divide both sides by 0.35
d = 76
She has 76 dimes and 76 + 2 = 78 quarters.
Lol just get a calculator and math paper. This is not cool, u aren't in college. Im in 7TH GRADE and I can do this garbage...
Answer:
697109 pennies
Step-by-step explanation:
First, you use the formula A = P (1 + rt).
R= rate which is 5.3%
T= time which is 7 years.
P is the principle which is 18790
A= is the answer
so first you multiply 7*5.3% which you get 0.371
then you multiply that with 18790 which then you get 6971.09
if you want pennies you multiply it with 100 to get 697109
