Answer:





maximum profit 
Step-by-step explanation:
Given that,
The company estimates that the initial cost of designing the aeroplane and setting up the factories in which to build it will be 500 million dollars.
The additional cost of manufacturing each plane can be modelled by the function.

Find the cost, demand (or price), and revenue functions.



Find the production level that maximizes profit.










Find the associated selling price of the aircraft that maximizes profit.


Find the maximum profit.
Manufacturing cost of one plane is:


maximum profit 

I think the pattern is that you multiply the first number by the second , then add the first number. SO:
e.g. for the first one 1 x 4 = 4 , 4 + 1 = 5
for the second one 2 x 5 = 10, 10 + 2 = 12...
So for 8+11:
you do 8 x 11 = 88 , 88 + 8 = 96
