Step-by-step explanation:
a.)Buying: total cost
Total cost= commission + (price per share× Number of of shares ) ;
Total cost= 10 + (11.06×500)=$5540
b.)Net gain or loss;
First, find cash received from sale of stock and deduct commission;
Cash from sale =10×500= $ 5000
deduct commission= 5000-10= $4990
Gain or loss= sale-cost = 4990-5540 = -$550, meaning there is a loss.
c.) Annual rate of return= (net gain or loss/amount paid)×100%
return= -550/(5540)×100 = -9.92%
1 yard=36 inches 1 foot=12 inches and 1/3 yard 1 inch= 1/36 yard and 1/12 foot
2(4 - 2r) = -2(r + 5)
First, divide both sides by -2. / Your problem should look like:
Second, regroup your terms. / Your problem should look like:
Third, add 4 to both sides. / Your problem should look like:
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like:
Fifth, subtract r from both sides. / Your problem should look like:
Sixth, subtract 2r - r to get r. / Your problem should look like:

Answer:
r = 9
Okay, are you saying:
-a = 2, b = 2, c = 2, solve (a + b + c)
or
-2a * 2b * 2c(a + b + c)
The total amount of hamburger that the manager of the store in the morning = 35.75 pounds
Quantity of hamburger sold to one customer during the day = 15.4 pounds
Quantity of hamburger sold to another customer during the day = 13.22 pounds
Total quantity of hamburger sold
by the manager during the day = (15.4 + 13.22) pounds
= 28.62 pounds
Then
The quantity of hamburger left in the store to sell = (35.75 - 28.62) pounds
= 7.13 pounds
So 7.13 pounds of hamburger is still left to be sold.
