You own a portfolio that is invested 43 percent in stock a, 16 percent in stock b, and the remainder in stock
docker41 [41]

Multiply the investment fraction by the corresponding return, and add the products. The given fractions add to 59%, so the remainder is 41%. (The total of the fractions is 100%—all of the portfolio.)

... 0.43*9.1% + 0.16*16.7% + 0.41*11.4%

... = 3.913% + 2.672% + 4.674% = 11.259%

Are carpet coast $15 per square metre. The total delivery charge is $21 Peter buys N squared metres of carpet what is the expres
postnew [5]

Answer:

15N + 21

Step-by-step explanation:

We are given that,

Amount of carpet bought by Peter = N meter²

The cost per meter square of the carpet = $15

So, the cost of 'N' meter square of carpet = 15N dollars.

Also, the delivery charge for the carpet = $21

Thus, the total cost of the carpet is given by,

Total cost = Cost per square meter + Delivery charge

i.e. Total cost = 15N + 21 (in dollars).

Hence, the expression representing the cost in dollars is '15N + 21'.
