1. Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(250)?

The house sold for $250,000.
The house stayed on the market for an average of 250 days before being sold.
This is the average number of days the house stayed on the market before being sold for $250,000.
The house sold on the market for $250,000 and stayed on the market for an average of 250 days before being sold.

2. Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the movie. Choose the cost function that represents this scenario if x equals the number of nights Laura has the movie.

c(x) = 2.00x + 0.50
c(x) = 2.00 + 0.50x
c(x) = 2.50x
c(x) = (2.00 + 0.50)x

Answer 1

Answer:c(x)=2.00 +0.05x

Explanation:

Answer 2

1. f(250)= ??? (the average number of days a house stayed on the market before being sold for $250,000.)
p=price=$250,000
For #1. I could see both
- The house sold for $250,000.
and

(f(250) is the average number of days the house stayed on the market before being sold for $250,000. ( I would guess this one BEST describes it though)

2. let x= number of nights with the movie

$2.00 is a one time charge. So, it will not have a variable next to it in the expression.

c(x)=2.00 +0.05x
