Kelly hired a decorator. The decorators total
charge, c, can be found using the equation c
27 12.5 h, where h represents the number of
hours the decorator works. Find the total charge
during which Kellys decorator worked 4 hours.
Can you build a table to represent this
relationship?

Sally purchased cans of soda that sold for .50
per can. The total cost of the sodas, c, depends
on the amount of sodas, s that she buys.
Complete the table to show this relationship.
1.50

Does this table represent the relationship
between cost and sodas? Why or why not?

A set of parentheses is missing from the
equations below. Place the parentheses to make
it a true statement.

The graph of the line y x 4 is shown
below. Construct a table to represent ordered
pairs that can be found on this line.

The expression shown below describes a pattern
of numbers.
-2 (n 1)
If n represents a numbers position in
the sequence, which pattern of numbers does the
expression describe?

Mr. Kangas 5th graders are planting a garden.
Each student will need materials that cost 3.00
and an 8-plant tray that costs 4.50. If x
represents the number of students in Mr. Kangas

total amount spent by Mr. Kangas students?

• y 8x (4.50 3.00)
• y 4.50 3x
• y 7.50x
• y (8x 3) 4.50
