Explanation:
Given that,
Adobe Systems stock = $3,000
Dow Chemical = $6,000
Office Depot = $7,000
Total Value of stock:
= Adobe Systems stock + Dow Chemical + Office Depot
= $3,000 + $6,000 + $7,000
= $16,000
Portfolio weights of Adobe Systems stock:
= Value of Adobe Systems stock ÷ Total Value of stock
= $3,000 ÷ $16,000
= 0.1875
Portfolio weights of Dow Chemical stock:
= Value of Dow Chemical stock ÷ Total Value of stock
= $6,000 ÷ $16,000
= 0.375
Portfolio weights of Office Depot stock:
= Value of Dow Chemical stock ÷ Total Value of stock
= $7,000 ÷ $16,000
= 0.4375
Answer:
The carpenter earned an extra $100.
Explanation:
Since this problem deals with a one-year loan with an yearly interest rate, it can be treated as a simple interest problem. For simple interests, the final value (Vf) can be found by multiplying the initial value (Vi) by one plus the interest rate (i) as shown below:

To find how much extra money the carpenter made in the first year, one should subtract the final value of loan from the $2,000 dollars down payment plus the extra $400 he collected for the year
.
Therefore, the carpenter earned an extra $100.
