First, let's take a look at what was given in the problem. We are looking for the loss that Mr. Ellison incurred when he invested in a stock. Each share that he bought was $3 dollars and he bought a total of 250 shares. Now if he would want to get the total price of how much he spent, we just have to multiply 3 with 250. We will get an answer of 750. Now do remember that he incurred a loss and not a gain, so the proper way to write the answer is (750) or -750. So the answer to this problem is D.) -750
