Answer:

Explanation:
You need to assume that the total <em>expenses</em> were equal to the<em> cost of the supplies</em>, i.e. there were not other expenses but the<em> $1,500 for supplies to sell.</em>
The total income or revenue was <em>$3,700</em>.
The <em>percentage of the expenses to the revenue</em> is:

Answer: $1,203.49
Explanation:
The equal contributions will be an annuity. The $3,500 already there will also grow at 6% for 3 years. Expression is;
8,000 = ( 3,500 * ( 1 + 6%)^3) + Contribution * Future value interest factor of annuity, 3 years, 6%
8,000 = 4,168.56 + Contribution * 3.1836
Contribution = (8,000 - 4,168.56) / 3.1836
Contribution = $1,203.49
Answer:
$46.51
Explanation:
The weighted arithmetic mean can be defined as:

Where n is the number of shares and P is the share price, then:

Based on this, the weighted arithmetic mean price per share is $46.51
Answer:
Explanation:
Forward excahnge rate/spot exchange rate = (1+rh)/(1+rf)
rh - periodic interest rate in the home currency
rf - periodic interest rate in the foreign currency
Forward/90 = [1+1%*180/360]/[1+2%*180/360]
Forward = 1.005/1.01 * 90 = 89.55
Forward rate is 89.55 yen/$
