Final answer:
Using a simple ratio and proportion calculation, it's determined that the landscaper would plant 5 bushes in a 20-foot section of land.
Step-by-step explanation:
The student's question involves a basic proportionality problem in mathematics. The landscaper plants 10 bushes in a 40-foot section. To find out how many bushes he would plant in a 20-foot section, we can set up a ratio as follows:
40 feet : 10 bushes = 20 feet : x bushes
Now, we solve for x by cross-multiplication:
40*x = 10*20
x = (10*20) / 40
x = 200 / 40
x = 5 bushes
So, the landscaper would plant 5 bushes in a 20-foot section of land.
