Short Answer: 1.5
Givens
OA = 12
OB = 9
O does not lie on AB
Argument
The order that these lines must be in is OBA. O is on your left, B is in the middle and A is on your right.
Mark your distances as follows.
OB = 9
BA = 3
Mark the midpoint of OA = M1
Mark the midpoint of OB = M2
M1 = 12 / 2 = 6 so M1 is 6 units from O
M2 = 9/2 = 4.5
The distance between the two midpoints is 6 - 4.5 = 1.5
Answer M1 - M2 = 1.5 <<<<
Nice problem: Thanks for posting.
Answer:

Step-by-step explanation:
For this case we have the following profit function:

And we are interested on find the profit after selling 700 pretzels, so we just need to replace X=700 into the profit function like this:

The profit function is on the figure attached. We see that for 0<X<217 we have negative profits, and for X>217 we will have positive values for the profit. And also we can see that for X=700 we have a profit of approximately 169.
