Ms. Boyrer is writing a program to compute ad costs. She needs to enter an algebraic representation of the costs of a local paper's ad. Express the cost of an ad f(x) with x lines as a function of x algebraically.

• (32.50 when x ≤ 6, 32.50 + 6(x − 6) when x > 6)

• (32.50 when x ≤ 3, 32.50 + 6(x − 3) when x > 3)

• (32.50 when x ≤ 4, 32.50 + 6(x − 4) when x > 4)

• (32.50 when x ≤ 5, 32.50 + 6(x − 5) when x > 5)

Roxanne set up the following split function which represents the cost of an auto classified ad from her hometown newspaper. If x is the number of lines in the ad, express the price c(x) of a classified ad from this paper in words.

• The cost is $31.50 for five or fewer lines, and $5.50 for each additional line.

• The cost is $30 for five or fewer lines, and $6 for each additional line.

• The cost is $33 for five or fewer lines, and $6 for each additional line.

• The cost is $32 for five or fewer lines, and $5 for each additional line.

A local Pennysaver paper charges f dollars for a five-line classified ad. Each additional line costs a dollars. Express the cost of an eight-line ad algebraically.

• (22.50 when x ≤ 9, 22.50 + 5.75(x-9) when x>9)

• (22.50 when x ≤ 8, 22.50 + 5.75(x-8) when x>8)

• (22.50 when x ≤ 7, 22.50 + 5.75(x-7) when x>7)

• (22.50 when x ≤ 6, 22.50 + 5.75(x-6) when x>6)

Find the mean, median, mode, and range for the data set: 5, 4, 6, 7, 6, 7, 8, 7

• mean = 6.5, median = 6.25, mode = 7, range = 4

• mean = 6.5, median = 6.25, mode = 6, range = 4

• mean = 6.25, median = 6.5, mode = 6, range = 4

• mean = 6.25, median = 6.5, mode = 7, range = 4

Billy is looking to sell his Camaro. He compiles these prices from the newspaper for cars just like his: $2,000; $19,900; $18,100; $17,500; and $20,000. Why is it more reasonable for Billy to use the median, rather than the mean, to get a reasonable estimated price for his car?

• There is an extremely high price, and the mean is resistant to extreme scores.

• There is an extremely low price, and the mean is resistant to extreme scores.

• There is an extremely high price, and the median is resistant to extreme scores.

• There is an extremely low price, and the median is resistant to extreme scores.
