What do interest rates mean?
- An interest rate indicates how expensive borrowing is or how lucrative saving is.
- Therefore, if you are a borrower, the interest rate is the sum you pay for borrowing money and is expressed as a percentage of the overall loan amount.
What is an example of interest rates?
The basic interest formula is as follows, for instance, if you take out a $20,000 loan with a five-year term and a 5% interest rate: $5,000 in interest results from multiplying $20,000 by.05 by 5.
PV=FV * (1+i)^-n
=200\1.125
= 177.78

Answer:
x + y = 104
0.05x + 0.25y = 22
x = 20 niquels and y = 84 quarters
Step-by-step explanation:
Each niquel is $0.05, and each quarter is $0.25
So if we have x niquels and y quarters, we can set this system of equations:
x + y = 104 (eq1)
0.05x + 0.25y = 22 (eq2)
If we multiply the second equation by 4, and then subtract it from the first equation, we have:
(eq2)*4: 0.2x + y = 88
(eq1) - 4*(eq2): 0.8x = 16
x = 20
Now finding y with the first equation:
20 + y = 104
y = 84
