Anyone can help? Gloria has a lunch account in the school cafeteria. The balance, f(x), in her account can be represented by the function f(x) = −1.50x + 40, where x is the number of meals purchased. Suppose −1.50 changed to −2.75. What does this mean in the context of the problem? (2 points)

Changing −1.50 to −2.75 means her initial balance has decreased.
Changing −1.50 to −2.75 means her initial balance has increased.
Changing −1.50 to −2.75 means the price per meal has decreased.
Changing −1.50 to −2.75 means the price per meal has increased.

	4x − y = −3
	y = −3x + 4
	y = 4x − 3 <My answer
