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

Jaelyn Horne · Answer 1

3d + $14.00 - $7.00 = $12.10; $1.70

Step-by-step explanation:

Let the cost of a drink be d.

3 drinks cost 3d. The pizza cost $14.00.

They had a discount of $7.00.

They paid $12.10.

The equation is:

3d + 14.00 - 7.00 = 12.10

3d + 7 = 12.1

3d = 5.1

d = 1.7

A drink costs $1.70.
