Overview: Two young men are earning money by cutting cords of wood.


 

 

Cutting Cordwood

Anthony and Jacob want to earn money to buy a new dog sled by selling cordwood to the residents of Fort Yukon. They have determined that together they can cut 1.8 cords of wood in an 8-hour day.

  1. How many cords can they cut in
    1. 2 days?


    2. 1 week?


    3. 1 month?


    4. 1 year?

     

  2. Find the algebraic expression for this situation. Define the variables you use.

 

 

  1. How many days will it take to cut
    1. 18 cords?


    2. 36 cords?


    3. 200 cords?

     

  2. What fraction of an 8-hour day is
    1. 4 hours?


    2. 5 hours?

     

  3. How many cords of wood can Anthony and Jacob cut in
    1. 4 hours?


    2. 5 hours?


    3. 1 hour?

     

  4. They earn $250 per cord of wood. How much will they earn by selling
    1. 10 cords?


    2. 20 cords?


    3. 5 cords?

     

  5. Write an algebraic expression for their earnings and explain your reasoning. Define any variables.

 

 

  1. If they begin next season with 10 cords already cut from the pervious season, how many will they have after
    1. 10 days?


    2. 20 days?


    3. 1 month?

     

  2. Fill in the following chart based on the information in #8.
