You can put this solution on YOUR website! 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 spend
a total of $13.20. Write an equation to model this
situation, and find the cost of one large drink.
Let X = the answer (the cost of one large drink).
13.00 + 4X - 6.00 = 13.20
Combine the 13.00 - 6.00, getting 7.00
7.00 + 4X = 13.20
Subtract 7.00 from both sides:
7.00 + 4X = 13.20
-7.00 -7.00
------------------
4X = 6.00
Divide both sides by 4
X = $1.50
