Final answer:
To find the approximate number of inches a pine tree will grow in 3 years, set up a ratio table using the given rate. Multiply the rate by the number of years to calculate the answer.
Step-by-step explanation:
To solve this rate problem, we can create a ratio table. The given information is that a pine tree grows about 18 inches per year. We need to find the approximate number of inches the tree will grow in 3 years.
We can set up a ratio table using the given information. In the table, the first column represents the number of years and the second column represents the number of inches the tree will grow:
YearsInches1183x
From the table, we can see that there is a constant ratio of 18 inches per year. To find the number of inches the tree will grow in 3 years, we can multiply the given rate by the number of years:
18 inches/year x 3 years = 54 inches
