Answer:
9% fund: $
210,000
13% fund: $70,000
Step-by-step explanation:
As she wants to have a $28,000 annual return for her $280,000 investment, she is expecting a return rate of 10%:

If we call x the proportion of the capital in the 9% fund, then (1-x) is the proportion of the capital in the 13% fund,and the return of the combination has to be the expected return of 10%:

Then, we know that 75% of the capital should be invested in the 9% fund and 25% in the 13% fund.
This correspond to a capital of:
9% fund: 0.75*$280,000 = $
210,000
13% fund: 0.25*$280,000 = $70,000
Answer:
A. 4 ounces
Step-by-step explanation:
Given that Elana paid $2.50 for 10 ounces of popcorn, let x be the amount popcorn a dollar will buy.
Thus we have:
$2.50 = 10 ounces
$1 = x
Cross multiply
$2.50 × x = 10 ounces × $1
Divide both sides by $2.50
($2.50 × x)/$2.50 = (10 ounces × $1)/$2.50
x = (10 ounces)/2.50
x = 4 ounces
Therefore, you can buy 4 ounces of popcorn per dollar
