Cab companies often charge a fiat fee for picking someone up and then charge an
additional fee per mile driven. pick a u. s. dty and research the rates of two
different cab companies in that city. find companies that charge different amounts
per mile and have different fiat fees. if you have trouble finding this information
for two companies, you can make up what you think would be reasonable prices
for a cab's flat rate and a cab's rate per mile.
task 1
a. for the first company, express in words the amount the cab company
charges per ride and per mile
b. write an equation in slope-intercept, point-slope, or standard form. explain
why you chose the form you did.
c. what do the slope and y-intercept mean in the context of this problem?
hint: what do you pay when you step into the cab?
task 2
for the second company, express in a table the cost of the cabide given the
number of miles provided
(see picture)
a. write an equation in slope-intercept, point-slope, or standard form. explain
why you chose the form you did.
b. what does the slope mean in the context of the problem?
task 3
cabs use a valuable commodity-gas! research average gas prices from 2005-2015 for the city you chose. if you can find this information for your specific city.
you can research national gas price averages instead
a. create a table showing the average gas price each year
b. create a scatter plot of the data in your table.
c. what equation models the data? what are the domain and range of
the equation? do you think your equation is a good it for the data?
explain how you determined your answers
d. is there a trend in the data? does there seem to be a positive correlation,
negative comention or neither
how much do you expect as to cost in 2020? explain
