Levi shovels the gravel he plans to purchase in a metal container that weighs 22 pounds. When there are 3 buckets of gravel in the metal container, the total weight of the metal container and the gravel is 67 pounds. When there are 4 buckets of gravel, the total weight (including the metal container) is 82 pounds.
Can't show an image but one is 22 pounds, another is 67 pounds, and the last is 82 pounds.
Which equation and graph match the situation?
y = 22x
y = 22x + 15
y = 15x + 22
y = 15x
Please help, thank you! :D
The correct equation that matches the situation is: y = 15x + 22
In this equation:
- y represents the total weight (including the metal container)
- x represents the number of buckets of gravel
This equation is correct because it accounts for the initial weight of the metal container (22 pounds) and the increase in weight for each additional bucket of gravel (15 pounds per bucket).
The graph of this equation will be a straight line that starts at (0,22) on the y-axis and has a slope of 15.
