The answer is A.

Solution:

·         (5, 2)

5*72 = 360

2*90 = 180

360 + 180 = 540

·         (3, 3)

3*72 = 216

3*90 = 270

216 + 270 = 486

·         (1, 4)

1*72 = 72

4*90 = 360

72 + 360 = 432

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
