Answer:
The interest rate of the account is 
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above and solve for r
![[(2,830.97/1,863)^{1/56}-1]=\frac{r}{4}](https://tex.z-dn.net/?f=%5B%282%2C830.97%2F1%2C863%29%5E%7B1%2F56%7D-1%5D%3D%5Cfrac%7Br%7D%7B4%7D)
![r=4*[(2,830.97/1,863)^{1/56}-1]\\ \\r= 0.03](https://tex.z-dn.net/?f=r%3D4%2A%5B%282%2C830.97%2F1%2C863%29%5E%7B1%2F56%7D-1%5D%5C%5C%20%5C%5Cr%3D%200.03)

Answer:
16
Step-by-step explanation:
Divide 64 by 8 to get 8. this is 1/8 of the books.
3/8 were non fiction, or 24
1/4 (2/8) were picture books, or 16
5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.
3/8 were chapter books, or 24.
add the amount of picture books and chapter books since they are the fictional texts.
16+24=40
subtract the amount of non fictional books from the amount of fictional books to get the sum.
40-24=16
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
