Hi! I hope this is helpful. :)

Answer:

The equation for the amount of money remaining on the card, A, in terms of the number of cups of coffee, x, is:

A = 30 - (30-12)/6 * x

Step-by-step explanation:

The equation represents the original amount of money on the card, $30, subtracted by the money spent per cup of coffee, which is (30-12)/6 times the number of cups of coffee, x.
