�
,
A, in terms of
�
,
x, representing the amount money remaining on the card after buying
�
x cups of coffee.

Answer:
�
=
A=

Answer 1

We can start by using the given information to find the initial value of the gift card, which is the value before Alexander started using it:

Initial value of gift card = $9 + 4 x $1.50 = $15

Let's use A to represent the amount of money remaining on the card after buying x cups of coffee. Each cup of coffee costs $1.50, so the amount spent on coffee after buying x cups is 1.5x. The remaining balance on the card can be found by subtracting the amount spent on coffee from the initial value of the card:

A = $15 - 1.5x

Therefore, the equation for A in terms of x is:

A = $15 - 1.5x
