QUESTION
Question #1:Expain!
Susan plans to visit an amusement park where she must pay for admission
and purchase tickets to go on the rides. Susan wants to find the total cost
for a day at the amusement park. She wrote the equation c = 1.5x + 12 to
predict c, the total cost for a day at the amusement park. What could the
number 12 represent in Susan’s equation:
A. The number of rides
B. The cost of admission
C. The cost of each
ticket
Explain why you think your answer is correct:
D. The number of tickets
Question #2:
The table to the right shows the cost of different numbers of goldfish at a
pet store.
The cost is a linear function of the number of goldfish. Which statement
describes the rate of change (slope) of this function?
A.
B.
C.
D.
