\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$9000\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{semi-annually, thus twice}
\end{array}\to &2\\

t=years\to &9
\end{cases}

A=9000\left(1+\frac{0.06}{2}\right)^{2\cdot 9}

Answer:

a) 2500 L b) 2250 L c) 98000 L d) 14.5 kg of rice, .725 kg of beef, 48.3 repeating kg of wheat.

Step-by-step explanation:

Ok so, this question looks intimidating but I promise it's not that bad.

a) They're asking how much water (L - meaning liters) would be needed for 25 baths.

To find this, they already give you how much water is needed for 1 bath. (100) Since this is the amount for 1 bath, we can find how much water is needed for 25 baths by multiplying 100 by 25. Your answer should be 2500 L of water.

b) This is the same thing again, but with wheat. They give us the information for how much wheat is used for 1 kg of wheat, which is 600 L. The question asks how much water would be needed to produce 3.75 kg of wheat, so we multiply 600 by 3.75 which equals 2250 L.

c) This is also the same thing but this time for beef. So we multiply 40000 by 2.45 which gives us 98000 L

d) To find this, we must divide 29,000 by the amount of water needed for 1 of each item, so we can find how much we would multiply the amount needed for 1 of each item in the first place (which is the amount of rice, beef, wheat)

So, 29,000/2000 = 14.5 kg of rice

29,000/40000 = .725 kg of beef

29,000/600 = 48.3 repeating kg of wheat.

I would like to know how to get the correct answer for this.
shusha [124]
For a problem like this, we have to think logically

we know that 6 * some number in the thousands must equal 25 thousand something. Let's say we put 5 in that first spot, 6 * 5,000 is already 30,000 so that's wrong. If we go one lower, 6 * 4,000 is 24,000 and so now we can include the 287 knowing it will fit.

so 6 * 4287 = 25,722.

all we do now is fill in the blanks to match our answer.
