A: Let x be the number of grills Kyle rented. If each grill cooked 28 hot dogs, how can we express the number of hot dogs that were cooked? |
||||||||
Number of hot dogs that were cooked = | 28 x | |||||||
B: Let y be the number of people who attended the cookout. If each person ate an average of 2 hot dogs, how can we express the number of hot dogs that were eaten? |
||||||||
The total hotdogs eaten = 2y |
||||||||
C: Set the number of hot dogs cooked equal to the number eaten plus the number remaining. This will give you a "hot dog" equation. |
||||||||
Hot dog equation: 28x = 2y + 4 | ||||||||
D: Repeat steps A through C for the burgers to obtain a "burger" equation. |
||||||||
Number of burgers cooked = 14x | ||||||||
The total burgers eaten = y | ||||||||
Burger equation: 14x = y+2 | ||||||||
E: Solve the equations to determine both the number of grills and the number of attendees. |
||||||||
Both equationsa re the same i.e the hot dog equation (28x-2y=4) reduces to 14x-y=2 by dividing the hot do equation by 2 | ||||||||
Thus, there are infinite solutions to the problem. In the table below are a few of those: | ||||||||
Equation: 14 x (Grills) - Attendees = 2 or Attendees =14 x Grills -2 | ||||||||
Number of grills: |
1 | 2 | 3 | 4 | 5 | |||
Number of attendees: |
12 | 26 | 40 | 54 | 68 | |||
