Answer:
option A
Step-by-step explanation:
Let x be the number of television sold
and y be the number of computer sold
An electronics store makes a profit of $72 for every television sold and $90 for every computer sold.
Profit for x television is 72x
Profit of y computer is 90y
Total profit is 72x+90y
sales profit is atleast 360
so inequality becomes 72x+90y >360
graph is attached below
(5,2) lies on the shaded part, so (5,2) is our solution
(3,3) lies on the shaded part, so (3,3) is our solution
(1,4) lies on the shaded part, so (1,4) is our solution
(4,0) (2,2) (1,1) and (1,0) does not lies on the shaded part
So option A is correct
