Respuesta :

Answer:

  $2.25

Step-by-step explanation:

Let c represent the cost of a cup of coffee. Then the total amount paid for 3 cups is ...

  3c + 3c·0.08 = 7.29

  3.24c = 7.29

  c = 7.29/3.24 = 2.25

A cup of coffee costs $2.25.

I don't know what a "pointd" is, but I suggest you not make promises you cannot keep.
