3-Variable Word Problems

Just when you thought you were done with 3 variables! We get word problems. But boy, are they fun! Here is a link to homework #16.

Coming Up:

- Benchmark 2.4 on Monday, 10/1

- Chapter 3 Test on Tuesday, 10/2

Posting for Points Question:

I need some help. For our next test we will have at least 1 word problem, probably 2 (a 2-variable and a 3-variable system). Create a problem and give the solution that would make a good word problem. You can model it after problems from the homework, but make sure it has a different solution. You might want to start with a solution and work backwards. Examples might include a problem with nickels, dimes, and quarters, or perhaps a something original. The best one goes on the test!

    Here’s my problem for now, but I might need to edit it a little more…post a comment if you have any questions!

    The state fair sold admission tickets in a price range of 3 different age groups: adults, teens, and children. The adult price was $16, the teen’s price $6, and the child’s price $4. A group of 26 people attended the fair together. The total price for all of them to enter the fair was $214. The number of teens in the group was double of the adults and children combined. How many adults, teens, and children were in the group?

    Mr. F, I keep trying to make one of these but when I try and make one and then do the problem my answers come out as fractions and then it doesn’t make sense as an answer.

    Sorry, for so many comments. I figured it out. I should have read your blog more carefully.

    Danielle has five dollar bills, ten dollar bills, and twenty dollar bills worth 205 dollars. The number of ten dollar bills is 3 times less than the sum of the five dollar bills and twenty dollar bills. How many of each time of coin does Danielle have if there are 17 dollars in all?

  7. I am already not very good at solving word problems…but now writing one is going to be even harder!!!!!!

The total amount the ballons cost were $48. How many red, blue, and green ballons are there?

    solve the problem to find how many athletes finished in each place.

    the miners won in saturdays track meet with the help of 20 individual event placers earning a combined 68 points. A first place finish earns 5 points, a second place earns 3 points and third place earns 1 point, the miners had a strong second place showing with as many second place finishes as the first and third combined .

    Darn, I made a mistake in the numbers… :( arrggghhh!

  12. Dani C. Per.1

    I think I needed to change the number of people to 24, and the total cost to $188… but you have already probably figured it out!

    The SPCA adopt-a-dog-athon earned a total of $5,000.
    The number of dogs plus the number of donations equals 70.
    If 20 dogs were adopted at $105 each, then how many donations were made? How much was the average donation?

    I still don’t really get these but it’s worth a shot…

    Bob has 76 pennies, dimes, and quarters. There are three times the amount of pennies that there are quarters, and twice as many dimes as quarters. All together the coins add up to $10.45. How many quarters are there?

    Umm.. I’m pretty sure that this doesn’t even work, and seeing that I don’t know how to figure them out, this could be a problem. haha
