Write and solve an equation for each situation. Be sure to define your variable.
Herman rents a bike for a set fee of $5 and a rate of $3 an hour. Jan rents a bike for $17. How many hours did she rent a bike for?
Jayson has 97 tickets to give away. He gave 4 tickets to each student in his class and has one leftover.
How many students in his class?
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
