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?

    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.

    Okay, look. Here's the only way i know how to explain it. -1.50 is the cost per meal x is the variable used to represent the # of meals Gloria eats. So if -1.50 changes to -2.75, what does that say about the equation?

    We already know that -1.50 is MORE THAN -2.75... What is happening to the cost per meal?

    Changing –1.50 to –2.75 means the price per meal has decreased.

    No. If the price of the meal was 1.50 you're spending one fifty therefore if the price goes from 2.75 then you're paying MORE.
