Gasoline (gallons)
To find out the number of gallons of gasoline Trisha can purchase, we need to locate the point on the graph where the cost ($30) intersects the y-axis.
Looking at the graph, we see that the cost of gasoline is $30 when X is between 5 and 10 gallons. However, we want to find the nearest whole number of gallons Trisha can purchase.
Since the point X is between the 10 and 12-gallon marks on the graph, we can conclude that Trisha can purchase approximately 11 gallons of gasoline (rounded to the nearest whole number).
Based on the given graph and the information provided, Trisha's mom gave her $30 to fill up the car's gas tank.
To determine the number of gallons of gasoline Trisha can purchase, we need to find the point on the graph where the cost is closest to $30.
Looking at the graph, we can see that the cost of gasoline decreases as the number of gallons increases. The cost is $25 for 5 gallons and $20 for 10 gallons. Therefore, the cost is likely to be between these two points.
Since Trisha's mom gave her $30, which is more than the cost of 5 gallons but less than the cost of 10 gallons, we can estimate that Trisha can purchase around 5-10 gallons of gasoline.
To determine the exact number of gallons, we need to find the point on the graph where the cost is closest to $30. However, the graph you provided does not show the exact cost at point X. Therefore, we cannot determine the exact number of gallons of gasoline Trisha can purchase.
