Let one factor be x. Second factor is 11 less than half of this factor, so second factor will be (0.5x - 11). The product of these two factors is -36.
So,
If,
x = 4, the other factor will be = 0.5(4) - 11 = - 9
If,
x = 18, the other factor will be = 0.5(18) - 11 = -2
So, there are two possible set of factors.
1) 4 and -9
2) -2 and 18
From these -2 and 18 is available in the options. So this is the correct answer.

For this case what we should do is find the cost per ounce.
For this, we can use the following rule of three:
5 ounces ----------------------> 2.50 $
1 oz ------------------------> x
From here, we clear the value of x.
We have then:
Answer:
The unit cost per ounce is given by:
x = 0.5 $ / ounce
