A.After 2 hours, the travel magician will have made $150.

B.After 300 hours, the travel magician will make $2.

C.After 2 hours, the travel magician will make $300.

D.After 150 hours, the travel magician will have made $2.

2.What is the minimum and maximum group size if the minimum charge to a bus rental is $200, the maximum charge is $300, and the cost is determined by the function f(x)=5x+50? Give your answer as a statement and in function notation.

A.The statement f(30)=300 means that the group size of 30 reaches the minimum charge for the bus rental of $300, and f(50)=200 means that the group size of 50 reaches the maximum charge for the bus rental of $200.

B.The statement f(50)=200 means that the group size of 50 reaches the minimum charge for the bus rental of $200, and f(30)=300 means that the group size of 30 reaches the maximum charge for the bus rental of $300.

C.The statement f(50)=300 means that the group size of 50 reaches the minimum charge for the bus rental of $300, and f(30)=200 means that the group size of 30 reaches the maximum charge for the bus rental of $200.

D.The statement f(30)=200 means that the group size of 30 reaches the minimum charge for the bus rental of $200, and f(50)=300 means that the group size of 50 reaches the maximum charge for the bus rental of $300.

3.The soda shop's profit for a day is modeled with the function f(x)=50x+30 where x is the number of days. How much did the shop make after 6 days?

A.$330

B.$300

C.$230

D.$270

Answer 1

#1 A. Clearly 2 is what you know, and 150 is what you calculate
#2 D. Read each choice carefully. It's the only one which makes any sense in the context
#3. f(6) = 50*6 + 30 = 330
