Answer:

4 ; 24

Step-by-step explanation:

A.)

Fixed fee, x = $5

Hourly rate, y = $3

Total rent fee, t= $17

Number of rent hours :

$17 = $5 + $3y

17 - 5 = 3y

12 = 3y

y = 12/3

y = 4 hours

B.)

Total Number of tickets , t = 97

Tickets per student, r = 4

Tickets left = 1

Number of students in class:

(97 - 1) / 4

96 /4

= 24 students
