hn and 4 friends are going out for pizza for lunch. They split one pizza and 5 large drinks. The pizza cost $10.00. After using
a $4.00 gift certificate, they spend a total of $13.50. Write an equation to model this situation, and find the cost of one large drink.
1 answer:
5d + 10 - 4 = 13.50 <== ur equation
5d + 6 = 13.50
5d = 13.50 - 6
5d = 7.5
d = 7.5/5
d = 1.50 <== what each drink costs
