Hi there!
The answer is A. The constant 900 represents the amount Kayla's bakery earns in a particular month when there are no online orders.
Since 900 is part of the cost that is added to the amount of money Kayla makes per online order (x), it must represent the amount Kayla's bakery makes without online orders.

0.6 x 0.4 = 0.24
0.28 + 0.24 = 0.52 is the area
