To graph the relationship between the number of bottles of water sold and the total cost, we can use the formula to calculate total cost based on the number of bottles sold.
The relationship is given by: \[ \text{Total Cost} = \text{Price per Bottle} \times \text{Number of Bottles Sold} \] Given that the price per bottle is $1.50, the formula can be written as: \[ \text{Total Cost} = 1.50 \times \text{Number of Bottles Sold} \]
Now, let's calculate the total cost for different numbers of bottles sold, from 0 to 6:
| Bottles Sold | Total Cost ($) | |--------------|-----------------| | 0 | 0 | | 1 | 1.50 | | 2 | 3.00 | | 3 | 4.50 | | 4 | 6.00 | | 5 | 7.50 | | 6 | 9.00 |
Plotting the Graph
- Horizontal Axis (x-axis): The number of bottles sold (0 to 6).
- Vertical Axis (y-axis): The total cost in dollars (0 to 10).
Coordinates to Plot
Based on the table, the coordinates to plot would be:
- (0, 0)
- (1, 1.5)
- (2, 3)
- (3, 4.5)
- (4, 6)
- (5, 7.5)
- (6, 9)
Drawing the Line
- Start plotting each of the points on the graph.
- Connect the points with a straight line, as the relationship is linear.
Additional Notes
- The line will start at the origin (0, 0) and move upward as you increase the number of bottles sold, reflecting the increase in total cost.
- The slope of the line represents the cost per bottle, which is $1.50 in this case.
This should help you visualize the relationship between the number of bottles sold and the total cost effectively.
