5. (ex. 8, p.142) COST ANALYSIS: A hot dog vendor pays $25 a day to rent a pushcart and $1.25 for the ingredients in one hot dog.
a Find the cost of selling x hot dogs in 1 day.
b) What is the cost of selling 200 hot dogs in one day.
c) If the daily cost is $355, how many hot dogs were sold that day?

it should be a and d. lmk if i'm wrong xd

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

other answer is correct. i had used the radius of the radius somehow. a website:

i think the answer is true
