John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.50. They spend a total of $16.40. Find the cost of one large drink.

one drink costs $1.30

Step-by-step explanation:

We know this by subtracting 12.50 from 16.40 you have the drinks leftover.

the remainder of the money is the three drinks. ($3.90)

By dividing the remainder by three, you get the price of one drink. ($1.30)

One large drink cost $1.30.

First, you find what three large drinks cost by subtracting the total (16.40) by the cost of the pizza (12.50), which equals $3.90.

You then divide 3.90 by 3 (the number of drinks bought) to get the answer $1.30
