Respuesta :

they leave a tip of $1.20, the total would be $9.20

Answer:

$9.2

Step-by-step explanation:

Four friends spend 8 dollars. However, they also leave a 15% tip. So, you will have to multiply .15 by 8. However that is not it. After, you have to add the product of that with 8. Which will give you 9.2.
