Question

4. Two student groups are working on the school yearbook. They printed two batches of pages on a printer in the computer lab. The table below shows the number of pages printed by each group and the time needed to print the pages. Time in Seconds (x) 30 20 Number of Pages (y) 150 130 Write ratios for the two print jobs in the form . Do the data represent a proportional relationship? Explain.​

Answer 1

The ratio for the first print job is 150/30 = 5 pages per second.

The ratio for the second print job is 130/20 = 6.5 pages per second.

Since the ratios are different, the data do not represent a proportional relationship. In a proportional relationship, the ratio between two variables remains constant.
