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.

Answer 1

Did u write an equation yet?

Answer 2

no, i dont understand how

Answer 3

You know what the meal costs right?

Answer 4

the total is 13.20 right?

Answer 5

Yes.

Answer 6

If you want to do an equation 13.20=? right?

Answer 7

I believe so. i think

Answer 8

You are right.

Answer 9

They only bought one pizza. How much did that pizza cost?

Answer 10

13 dollars?

Answer 11

Correct.

Answer 12

So 13.20=13.00? We put on the question mark because their is still more to the problem.

Answer 13

How many drinks did they buy?

Answer 14

well it has 4 possible choices.
4d + $13.00 – $6.00 = $13.20; $1.55
4d – $13.00 + $6.00 = $13.20; $6.73
4d + $13.00 – $6.00 = $13.20; $1.60
3d + $13.00 – $6.00 = $13.20; $2.07
and i dont understand what any of it means

Answer 15

Well they bought 4 drinks so that eliminates choice d. right? Since they used the variable d to represent the cost of the drinks.

Answer 16

right.

Answer 17

The cost of the pizza would add on to the cost of the drinks. What answer choice does that eliminate?

Answer 18

add on=+

Answer 19

is the answer #1?

Answer 20

Yes, but how did you get to that conclusion?

Answer 21

well i was looking at the last numbers and i dont think a drink would cost 6.73. so it eliminated that

Answer 22

i guess i used logic

Answer 23

What you needed to do was subtract 13.00 from both sides and + 6.00 to both sides. Then you would have 6.20=4d. divide each side by 4 then u would have 1.55=x Good job anyway though. Good luck on your test or whatever you are doing, thanks for fanning me, and please give me a medal!

Answer 25
