Daily Dilemma #9: Answer Key

 

  1. 2 teams each catch 5 catfish: 10 X 3 = 30 pts.

    1 team catches 4 pinfish: 4 X 9 = 36 pts.

    1 team catches 2 pinfish: 2 X 9 = 18 pts.

    Total points = 84
  2. Total perimeter of the pool is 2(5+9) = 28 meters. She needs 28 – 19 = 9 additional meters of fencing. Her cost is 9 X $8.75 = $78.75.

     

  1. 1st day: 7 – 2 = 5 miles
    2nd day: 5 + 7 – 2 = 10 miles
    3rd day: 10 + 7 – 2 = 15 miles
    4th day: 15 + 7 = 22 miles

So, on the 4th day the train gets to the top of the hill.
