Examine the rise in gasoline prices from 1997 to 2006. The price of regular unleaded gasoline in January 1997 was $1.26 and in January 2006 the price of regular unleaded gasoline was $2.31 (Bureau of Labor Statistics, 2006). Use the coordinates (1997, 1.26) and (2006, 2.31) to find the slope (or rate of change) between the two points. Describe how you arrived at your answer.
Let 1997 (base year) correspond to year 0. Then 2006 corresponds to year 9
t1 = 0, t2 = 9
The corresponding per gallon prices are c1 = 1.26, c2 = 2.31
Slope = Time rate of change of price = (c2 – c1)/(t2 – t1)
Slope = (2.31 – 1.26)/(9 – 0) = 1.05/9 = $0.1167 per year (= 12 cents per year)
Over those 9 years from 1997 to 2006, the gas price per gallon has increased by an average 12 cents.
The linear equation
represents an estimate of the average cost of gas for year x starting in 1997. The year 1997 would be represented by x = 1, for example, as it is the first year in the study. Similarly, 2005 would be year 9, or x = 9.
What year would be represented by x = 4?
What x-value represents the year 2018?
What is the slope (or rate of change) of this equation?
What is the y-intercept?
What does the y-intercept represent?
Assuming this growth trend continues, what will the price of gasoline be in the year 2018? How did you arrive at your answer?
(a) x = 4 corresponds to the year 2000
(b) Year 2018 corresponds to x = 22
(c) Slope = Rate of change = 0.15
(d) y-intercept = 0.79
(e) It represents the average cost of gas just prior to the period of stu ...

1. Suppose you are at the gas station filling your tank with gas. The function C(g) represents the cost C of filling up the gas tank with g gallons. Given the equation:
a) What does the number 3.03 represent?
The number 3.03 represents the price of 1 gallon of gas.
b) Find C(2)
3.03(2) = 6.06
c) Find C(9)
3.03(9) = 27.27
d) For the average motorist, name one value for g that would be inappropriate for this function’s purpose. Explain why you chose the number you did.
