GP 2 Week 5

This is a two part question
If you buy 5 candy bars and a bag of $4.00 gummy worms, the variable expression 5c + 4 represents the total cost of the purchase.

1) If your bill came to $21.00 how much did each candy bar cost?

Suppose the next day you went back to the store and bought 3 DVDs and a video game for $30.  2) Write a variable expression to represent this purchase

  1. Each candy bar cost 3.24 dollars... because you simply plug the numbers in the equation.
    3d plus 30 is the answer. meaning u bought three dvd`s plus a thirty dollar amount.

  2. 1) Each candy bar would cost $3.40. If you do 21=5c+4, it's a 2 step equation. So when you solve it you get $3.40.

    2) 3d+30

    1. I agree with Alexus because, if you subtract the 4 dollar bag of gummy bears from the 21 total amount paid, you will get 17 dollars. And if you divide that by the 5 candy bars, the answer is 3.4. So each of the candy bars are $3.40.

      3d+30

    2. I Agree With Alexus Because Once You Do The Whole Equation You're Left With 3.4. Since We're Talking About Money We Make It $3.40. Each Candy Bar Costs $3.40.

    3. I agree with Alexus. You have to put it in a equation and it would be 21=5c+4 and u will get 3.40. It would be 3d+30.

  4. 1). 21.00-4.00=17.00. If you divide 17.00 and 5 you'll get 3.40.

    2). 3D+30

  5. 21=5c+4
    -4 -4
    17=5c
    /5 /5
    3.4=c
    1, Each candy bar would cost 3.40 because when you do the 2 step equation the total would be 3.4.
    2, The equation would 3D+30

    1. I agree with Rayshaun because i did the two step equation and i got 3.40 and also for 2.) i got 3d+30 as well

  12. For the first part of the equation you would do 21 = 5c + 4 which when you solve it it would cost 3.40.For the second part of the equation.You would put in the form 3d+30

  13. If I use the equation given 5c+4.00 I get that the cost of each candy bar would be $3.40. The equation I would use to represent the purchase at the video store is 3d=$30. I would use this equation because you buy 3 DVD,s and you spend $30 on a video game.

  14. Each candy bar cost $3.40.
    I got this by 5c=4=21 which c comes out to 3.40
    The second part is 3d+30

  16. 1.) i took 5 and multiply it by 3.4 and got 17. the i took 17 and added 4 to it so i got a total of 21.
    2.) 3d+30

    21-4 is 17 and 17 divided by 5 is 3.40
    2.) 3D+30

  19. The candy is $3.40.
    I did 21-4 and I got 17 and then I got 3.40 because I divided 17 by 5.
    The second part would be 3D+20

  20. Each of the candy bar is $3.40. Beacause if u set up the equation right which is 21=5c+4 which equal to $3.40.

    2: 3D+30

  21. The candy is $3.40.
    I had did 21-4 and gotten 17 and then I had gotten 3.40 dollars by dividing 17 with 5.
    The second part would be 3D+20.

  23. Each candy

    because you simply plug the numbers in the equation. 3d plus 30 is the answer. meaning u bought three dvd`s plus a thirty dollar amount.
