Answer :
The profit at point (0,5) is, 400
The profit at point (1,12) is, 1010
The profit at point (4,10) is, 1000
Step-by-step explanation :
Coordinates : It is a set of values which show an exact position on a graph.
There are two variables or coordinates that are x-coordinate and y-coordinate.
As we are given that function:

where,
P = profit
x and y are the coordinates.
(1) Now we have to calculate the profit at point (0,5).

x = 0 and y = 5



The profit at point (0,5) is, 400
(2) Now we have to calculate the profit at point (1,12).

x = 1 and y = 12



The profit at point (1,12) is, 1010
(3) Now we have to calculate the profit at point (4,10).

x = 4 and y = 10



The profit at point (4,10) is, 1000
