Question 197924: 2. Suppose Bob owns 2,000 shares of Company X and 10,000 shares of Company Y. The total value of Bob's holdings of these two companies is $340,000.
Suppose Frank owns 8,000 shares of Company X and 6,000 shares of Company Y. The total value of Franks holdings of these two companies is $340,000.
a. Write equations for Bob and Frank's holdings. Use the variables X and Y to represent the values of shares of Company X and Company Y.
b. Solve for the value of a share of Company X and Company Y. Show your work so you can get partial credit even if your final answer is wrong.

Question 198059: 3. Take a look at the table below and write out an equation for f(x).
x -2 -1 0 1 2
f(x) -2 2 6 10 14
each of these items (x, -2, -1, 0, 1, 2) are suppose to be in a block in the first row of the table and (f(x) , -2, 2, 6, 10, 14 are on the next row of the table. The table just didn't copy over when I cut and pasted.
I am so lost in this algebra class, I don't even know where to begin with this, little alone find an answer. Please answer. Thank you

Question 198193: Suppose you have a hot dog stand, and when you charge $1 per hot dog you sell 75 hot dogs. But when you raise your price to $2 you only sell 50 dogs. Write an equation for the number of hot dogs you sell as a function of the price you charge. Use "H" for number of Hot dogs, and "P" for the price you charge for your hot dogs. You can assume the function is linear.
