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.

a. 3d + $14.00 – $7.00 = $12.10; $1.90

b. 3d – $14.00 + $7.00 = $12.10; $9.55

c. 3d + $14.00 – $7.00 = $12.10; $1.70

d. 2d + $14.00 – $7.00 = $12.10; $2.55

The equation to model this situation is  3d + $14.00 – $7.00 = $12.10 and the cost of one large drink is $1.7 .

Option (C) is correct .

Step-by-step explanation:

As given

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.

let us assume that the numbers of large drinks are represented by d .

Than the equation becomes

Total money spend = Number of drinks × d + Pizza cost  - Gift certificate amount .

Putting all the values in the above

12.10 = 3d + 14.00 - 7.00

Simplify the aboves

12.10 = 3d + 14 - 7

12.10 = 3d + 7

12.10 - 7 = 3d

5.1 = 3d

d = $ 1.7

Therefore the equation to model this situation is  3d + $14.00 – $7.00 = $12.10 and the cost of one large drink is $1.7 .

Option (C) is correct .
