Question

John and 3 friends are going out for pizza for lunch. They split one pizza and 4 large drinks. The pizza cost $13.00. After using a $6.00 gift certificate, they spent a total of $13.20. Write an equation to model this situation, and find the cost of one large drink.

Answer 1

Hello Whitegirl1998! :)



Let's write an equation for this!

The pizza was $13 and plus the drinks were 4 multiplied by n (n since we don't know the cost)

13+4*n

Now, we gotta minus the $6 from the total

(13+4*n)-6=13.20

Next, we must find what equals n.
