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:

Without additional context about the variables and the original cost - structure, we assume that \(s\) represents the cost of a student ticket. Option B correctly interprets \(s = 3.5\) as the cost of each student ticket being \(3.5\) dollars and makes a reasonable follow - up statement about the cost of an adult ticket (assuming a relationship between adult and student ticket prices). Option A has no basis as there is no indication of the number of adult and student tickets in relation to the value of \(s\). Option C misidentifies \(s\) as the adult ticket cost. Option D has no indication that the \(5\) - dollar discount is related to reducing the student ticket cost to \(3.5\) dollars.

Answer:

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