Question

a gardener recommends planting a certain tree 22 in. apart from each other. erica would like her trees to grow on one side of her 22-ft. driveway. how many trees will erica need? question help: message instructor

Explanation:

Step1: Convert units

First, convert the length of the driveway from feet to inches. Since 1 foot = 12 inches, a 22 - ft driveway is \(22\times12 = 264\) inches long.

Step2: Calculate number of intervals

The distance between each tree is 22 inches. The number of intervals between the trees is \(\frac{264}{22}=12\).

Step3: Determine number of trees

When planting trees along a length, the number of trees is one more than the number of intervals (because we plant a tree at the start). So the number of trees is \(12 + 1=13\).

Answer:

13
