Question

The graph shows the cost of gasoline at a gas station. Find the cost in dollars per gallon

Answer 1

Answer:

7/2 or 3.5

Step-by-step explanation:

The y-axis represents the cost is dollars. The x-axis is the amount of gasoline in gallons. To find the cost in dollars per gallon, choose a point on the graph, and divide the dollars (y-coordinate) by the gallons (x-coordinate).

cost = (21/4) / (3/2)

cost = 21/4 * 2/3

cost = 42/12

cost = 7/2 = 3.5
