C. Number of Days 30 60 120 240 480 Number of Stories 2 4 6 8 10

D. Number of Days 90 225 400 680 960 Number of Stories 3 6 9 12 15

Answer 1

The correct answer option is B. Number of Days 120 240 360 480 600 Number of Stories 5 10 15 20 25.

Explanation:

We are given some tables showing the number of stories completed in the construction of four different high-rise buildings and the number of days spent working on the building.

We are to determine whether which table represents a linear relationship.

Table B represents a linear relationship since its ratio of number of days to number of stories completed is constant.

Number of Days 120 240 360 480 600

Number of Stories 5 10 15 20 25

Ratio 24 24 24 24 24
