Question

part b
which interpretation is true when s = 3.5?
oa the total amount spent on 3 adult tickets and 4 student tickets is $3.50 after using the $5 discount.
ob each student ticket costs $3.50, which means the cost for each adult ticket is $7.
oc each adult ticket costs $3.50, and the cost of each student ticket is $5.
od the $5 discount reduces the cost of each student ticket to $3.50.

Explanation:

Since \(s = 3.5\), it is most likely that \(s\) represents the cost of a student - ticket. There is no information suggesting a relationship between student - ticket cost and adult - ticket cost in the problem statement other than the value of \(s\) itself. Option A refers to a total amount which is not indicated by \(s = 3.5\). Option C misidentifies \(s\) as the adult - ticket cost. Option D implies a discount relationship which is not supported by just \(s = 3.5\). Option B correctly interprets \(s\) as the cost of each student ticket.

Answer:

B. Each student ticket costs $3.50, which means the cost for each adult ticket is $7.
