Simone buys bus passes to travel to the city. The cost of 15 bus passes costs $36. Which graph has a slope that best represents the average cost of the bus passes in dollars per bus pass?
The best graph that represents the average cost of the bus passes in dollars per bus pass would be a straight line with a positive slope.
If the cost of 15 bus passes is $36, then the average cost of one bus pass can be found by dividing the total cost by the number of bus passes, which is $36 divided by 15, giving $2.40 per bus pass.
Therefore, the slope representing the average cost per bus pass would be $2.40 per bus pass.
The graph that best represents this slope would be a straight line with a slope of $2.40, moving upwards from left to right.
