Answer:
$2.69
Step-by-step explanation:
We can divide the cost in dollars to the gallons of gasoline to find the rate of change.
16.14 / 6 = $2.69
21.52 / 8 = $2.69
24.21 / 9 = $2.69
32.28 / 12 = $2.69
53.80 / 20 = $2.69
This means that each gallon costs $2.69, in other words this is the rate o change.
Best of Luck!
