To calculate the rate of change in the cost of gas as each gallon is pumped, we need to find the slope of the line passing through the points (15, 8) and (30, ?).

Let's first calculate the cost of gas when 30 gallons are pumped by using the given points:

At 15 gallons: $8
At 30 gallons: $16

Now, let's find the slope using the formula:

Slope (m) = (y2 - y1) / (x2 - x1)
= (16 - 8) / (30 - 15)
= 8 / 15
= 0.5333

Therefore, the rate of change in the cost of gas as each gallon is pumped is $0.53.
