A pizza company charges $50.40 for 3 pizzas and 12 drinks. A pizza is $10.80 more than a drink. What is the cost of each drink?

1.

$1.20

2

$1.50

$2.40

$2.50

A drink costs $1.20

Step-by-step explanation:

Step 1: Make a system of equations

50.40 = 3p + 12d

p = 10.80 + d

Step 2: Plug in p for the other equation

50.40 = 3 (10.80 + d) + 12d

50.40 = 32.40 + 3d + 12d

50.40 - 32.40 = 15d + 32.40 - 32.40

18 / 15 = 15d / 15

1.20 = d

Answer: A drink costs $1.20
