The scatter plot represents the amount of money, y, in dollars, a high school booster club makes while selling concessions at seven different basketball games with x people in attendance at each game. Which statement is true?

Back

The scatter plot shows a correlation but does not necessarily imply that there must be causation between the amount of money the booster club makes and the number of people in attendance at the basketball games.

A hotel charges customers $180 per night to rent a room and charges an additional one-time parking fee of $30. Which function represents the total cost, C(t), in dollars, of staying at the hotel for t days, where 0 ≤ t ≤ 14? Options: C(t) = 30t - 180, C(t) = 30t + 180, C(t) = 180t - 30, C(t) = 180t + 30

Back

C(t) = 180t + 30

A sales representative works at a technology store and can choose between two different pay plans: Pay Plan 1: Earn a flat rate of $755 per week. Pay Plan 2: Earn a flat rate of $485 per week plus 15% of the total weekly sales.
