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. 4d – $13.00 + $6.00 = $13.20; $6.73

b. 4d + $13.00 – $6.00 = $13.20; $1.55

c. 4d + $13.00 – $6.00 = $13.20; $1.60

d. 3d + $13.00 – $6.00 = $13.20; $2.07

If John and 3 friends ordered pizza for $13.00 and they paid $13.20 where in they also used the $6.00 gift certificate. Then we can deduce that the total amount of the bill was $13.20 + the gift certificate which is $6.00 which is equal to $19.20 and since the pizza was for $13.00 then we can deduct this from the total bill to get the amount of the drinks, ergo $19.20 - $13.00 = $6.20 since there were 4 large drinks so we divide the total amount of the drinks to the number of drinks. We would have $6.20 / 4 = $1.55 / large drink.

So the answer would be:

B. 4d + $13.00 – $6.00 = $13.20:$1.55

answer: i think the answer is etheir c or d but i don't know which one but have a good day!
