Answer:

Explanation about the mistake below

Step-by-step explanation:

Formulas

Sometimes the smallest error in the formula leads us to wrong and senseless results.

The formula you are trying is a well-known formula to compute financial variables. Let me write you down the correct formula

$\displaystyle P=d\cdot \frac{1-(1+r/k)^{-nk}}{r/k}$

You can check the mistake in the exponent of the parentheses. If we apply this formula with your numbers, we get

$\displaystyle 1836=d\cdot \frac{1-(1+0.085/12)^{-12}}{0.085/12}$

$1836=d\cdot 11.47$

Solving for d

d=160.14

Clare mixes 2 1/2 cups of water with 1/3 cup of orange juice concentrate Han mixes 1 2/3 cups of water with 1/4 cup of orange ju

Mkey [24]

<h2>Hans concentration is greater.</h2>

Step-by-step explanation:

$Concentration=\frac{\text{number of cups of orange juice}}{\text{number of cups of orange juice+number of cups of water}}$

For Clare,

$\text{number of orange cups}=\frac{1}{3} \\\text{number of water cups}=\frac{5}{2}$

Concentration= $\frac{\frac{1}{3} }{\frac{5}{2} +\frac{1}{3}} =\frac{\frac{1}{3}}{\frac{17}{6} }=\frac{2}{17}=0.117$

For Han,

$\text{number of orange cups}=\frac{1}{4}\\\text{number of water cups}=\frac{5}{3}$

Concentration= $\frac{\frac{1}{4} }{\frac{5}{3} +\frac{1}{4}} =\frac{\frac{1}{4}}{\frac{23}{12} }=\frac{3}{23}=0.130$

So,Hans concentration is greater.

If 3 dozen apples is $4.50, how much is each apple?

nalin [4]

The answer to the question asked above is as follows:

1 dozen = 12 pieces
3 dozen = (12 pieces)(3) = 36 pieces
thus :
If 3 dozen apples is $4.50 , each piece would be $4.50 / 36 pieces.

So $0.125 per piece of apple.

Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
