Question

Each tile costs $12. Determine the cost of 60 tiles, 80 tiles, 100 tiles, and 120 tiles. Write a set of ordered pairs (number of tiles, total cost) to represent the data. Then graph the ordered pairs.

A) (60, $720), (80, $960), (100, $1200), (120, $1440)
B) (60, $720), (80, $960), (100, $1000), (120, $1200)
C) (60, $720), (80, $800), (100, $1000), (120, $1200)
D) (60, $600), (80, $800), (100, $1000), (120, $1200)

Answer 1

The cost of each tile is $12. To determine the cost of a certain number of tiles, multiply the number of tiles by the cost of each tile. The set of ordered pairs is (60, $720), (80, $960), (100, $1200), (120, $1440).

Step-by-step explanation:

The cost of each tile is $12. To determine the cost of a certain number of tiles, you need to multiply the number of tiles by the cost of each tile. For example, to determine the cost of 60 tiles, you multiply 60 by $12, which gives you $720. Similarly, for 80 tiles, the cost would be 80 x $12 = $960. Continuing this calculation, the cost of 100 tiles would be 100 x $12 = $1200, and the cost of 120 tiles would be 120 x $12 = $1440.

To represent this data as a set of ordered pairs, you can use the number of tiles as the x-coordinate and the total cost as the y-coordinate. So the set of ordered pairs would be (60, $720), (80, $960), (100, $1200), and (120, $1440).

Graphing these ordered pairs will give you a straight line that goes through the points on the coordinate plane.
