the price of fuel may increase due to demand and decrease due to overproduction. george is studying the change in the price of two types of fuel, a and b, over time.

the price f(x), in dollars, of fuel a after x months is represented by the function below:

f(x) = 2.27(0.88)x

part a: is the price of fuel a increasing or decreasing and by what percentage per month? justify your answer. (5 points)

part b: the table below shows the price g(m), in dollars, of fuel b after m months.

m (number of months) 1 2 3 4
g(m) (price in dollars) 3.44 3.30 3.17 3.04

which type of fuel recorded a greater percentage change in price over the previous month? justify your answer. (5 points)

answer:

part a. the standard form of a rate equation is:

  y = ao (1 + r)^x

where,

ao = represents the initial value

r = represents the rate of growth

therefore rewriting the given f(x) equation in this form:

f(x) = 2.96 (1 + 0.04)^x

r = 0.04 = 4%

hence, the price of fuel a is increasing each month by 4%.

we can prove this by assuming two values of x = 1 and 2 and getting the ratio:

f(x=2) / f(x=1) = 2.96(1.04)^2 / 2.96(1.04) = 1.04

since ratio is 1.04, therefore there is in fact a 4% increase.

part b. to determine the growth rate of fuel b, let us take the ratio of months 1 and 2.

3.22 / 3.04 = 1.06

r = 0.6 = 6%

therefore the fuel with a greater percentage change in price per month is fuel b.
