Hot Dog Sales - Rental of Barbeque The Social Justice Club is going to rent a mammoth barbeque to cook the hot dogs for the hot dog sale. After contacting three rental companies in town, you have found out that each one will deliver and pick up their barbeque. The cost of propane is included in the rental. The rental costs are indicated below.

Rental A: $15/h

Rental B: $5/h + 50

Rental C: $9/h + 20

1)Write an equation that models the rental cost, C, for each company.
2)Graph all three models onto the same set of coordinate axis.
3)Which rental company should be chosen if you use the barbeque during lunch (11:05 - 12:30) and keep the barbeque to continue sales during the football game that will end about 4:30? Justify your answer.
4)Which rental company should be chosen if your school lunch hours run from 11:05 - 12:30? Justify your answer.
5)Which rental company should be chosen if your school returned the barbeque the following day? Justify your answer.

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
