John and 2 friends are going out for pizza for lunch. they split one pizza and 3 large drinks. the pizza cost $14.00. after using a $7.00 gift certificate, they spend a total of $12.10. write an equation to model this situation, and find the cost of one large drink. 3d + $14.00 – $7.00 = $12.10; $1.90 3d – $14.00 + $7.00 = $12.10; $9.55 3d + $14.00 – $7.00 = $12.10; $1.70 2d + $14.00 – $7.00 = $12.10; $2.55
