Question

A few precalculus students are planning a summer road trip to visit friends and do some math-themed sightseeing. They plan to begin their trip from Augsburg. 1. The students will be renting camping equipment from Quality Rentals for their trip so that they can enjoy the great outdoors! The cost of their equipment rental is defined by the piecewise function Q(x) =( 40x + 100, 0 ? x < 7 (400, 7 ? x where x is the number of days they rent the equipment. (a) Graph the function by hand. Be clear with notation, and include labels to demonstrate your understanding. (b) The point (6, 340) falls on the graph. Consider the scenario stated in this problem. What does that point represent in the context of the story? (c) They have a 15% off coupon on the equipment rental. This means that there is a discount function D(x) = 0.85x, where x is the original price of the rental. Compose the two functions to define a new piecewise function, P(x), that shows the discounted price for any number of days. Determine the order in which the function should be composed and explain your reasoning. (d) For the first 6 days of the trip, they’ll need to also rent some specialized equipment for boating. The cost of the boating equipment is described by the function B(x) = 80x + 250 where x is the number of days. Determine the function, T(x), that defines the total trip cost of the discounted camping equipment and the boating equipment for the first 6 days. Your answer to this part should not just be a number.

          A few precalculus students are planning a summer road trip to
visit friends and do some math-themed
sightseeing. They plan to begin their trip from Augsburg.
1. The students will be renting camping equipment from Quality
Rentals for their trip so that they can
enjoy the great outdoors! The cost of their equipment rental is
defined by the piecewise function
Q(x) =( 40x + 100, 0 ? x < 7
           (400,     
    7 ? x
where x is the number of days they rent the equipment.
(a) Graph the function by hand. Be clear with notation, and include
labels to demonstrate your
understanding.
(b) The point (6, 340) falls on the graph. Consider the scenario
stated in this problem. What does
that point represent in the context of the story?
(c) They have a 15% off coupon on the equipment rental. This means
that there is a discount
function D(x) = 0.85x, where x is the original price of the rental.
Compose the two functions to
define a new piecewise function, P(x), that shows the discounted
price for any number of days.
Determine the order in which the function should be composed and
explain your reasoning.
(d) For the first 6 days of the trip, they’ll need to also rent
some specialized equipment for boating.
The cost of the boating equipment is described by the
function
B(x) = 80x + 250
where x is the number of days. Determine the function, T(x),
that defines the total trip cost of
the discounted camping equipment and the boating equipment for the
first 6 days. Your answer
to this part should not just be a number.
