Question

The table shows the heights y (in centimeters) of a plant after x weeks. How many centimeters does the plant grow in one week

Answer 1

Answer: 20cm

Explanation:

Based on the table, we have the heights of plants after 0, 6, 12 weeks. Since one week is between 0 and 6, we know that the centimeters will be between 17 and 35.

If we take a look at the centimeters, we can see that every 6 weeks, the plants grow by 18cm. Since plants grow 18cm in 6 weeks, we get 18÷6=3cm.

This means we know the plant grows 3cm per week.

17+3=20cm
