The rate of change in the cost of the gas as each gallon is pumped can be determined by finding the slope of the line that passes through the given points (4,15) and (8,30).
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the given points:
m = (30 - 15) / (8 - 4)
m = 15 / 4
m = 3.75
Therefore, the rate of change in the cost of the gas as each gallon is pumped is $3.75.
A graph of the cost of gas purchased depending on the number of gallons pumped has the points (4,15) and (8,30) . What is the rate of change in the cost of the gas as each gallon is pumped?(1 p
