The cost of renting a wave runner is $20 plus $15 for each
hour the wave runner is rented for. Which equation can be
used to find the cost c, for renting the wave runner of h
hours?
Multiply $15 times the
number of hours (h)
that the wave runner is
rented for…
Add to this,
the $20
fee.
A. c  20  15
B. c  20h  15
C. c  15h  20
D. c  20  15h
15h  20
Mr. Silverman has 25 students in his refrigerator repair
class. If each student needs 50 file cards, which equation
can be used to find c, the total number of file cards?
Multiply 50 file cards
times the 25 students
in the repair class…
50  25
F. c  50  25
G. c  50  25
H. c  50  25
I. c  50  25
The cost of renting a ball room for the school dance is $250
plus $1.00 for each student s, who attends. If the total
cost c, of the dance is to be equally split among the 6th , 7th ,
and 8th grade student council, which equation could be used
to show the cost for each grade?
Multiply 1.00 times the
number of students (s)
who attend the dance…
This is added
to the $250
fee to rent
the ball
room…
( 250  1.00 s)  3
A. c  250s  1.00  3
B. c  250 1.00s   3
C. c  250 s  3
D. c  250 1.00s   3
Take the
total cost,
and divide it
by 3 (three
classes)…
Cablevision charges a fixed monthly charge plus $4.95 for

Subtract $4.95
to find the
monthly cost with
zero movies
rented…
Which equation correctly shows the relationship
between T and n ?
F. T  4.95n  34
G. T  n  4.95
H. T  4.95n  38.95
I. T  4.95n  38.95
$38.95  $4.95  $34
The cost would be $4.95
times the number (n) of
movies watched plus the
$34 monthly charge…
