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 spend a total of $13.20. Write an equation to model this situation, and find the cost of one large drink. a. 3d + $13.00 – $6.00 = $13.20; $2.07 b. 4d + $13.00 – $6.00 = $13.20; $1.55 c. 4d – $13.00 + $6.00 = $13.20; $6.73 d. 4d + $13.00 – $6.00 = $13.20; $1.60

Answer 1

The large drink will cost 1.55. 

Answer 2

 4d +13.00 -6.00 = 13.20

4d = 7.00 = 13.20

4d = 6.20

d - 6.20/4 =1.55

 answer is B
