Kelly and Greta are asked to write an equation for the scenario below.
“One person was able to plant 4 trees in the same amount of time that 5 people working together were able to plant 20 trees.”
The girls agree that x represents the number of people working and y represents the number of trees planted. Kelly wrote the equation y = one-fourth x, and Greta wrote the equation y = 4 x. Which person is correct, and why?
Kelly is correct; each person plants One-fourth more trees than the person before them.
Kelly is correct; 1 = one-fourth times 4 and 5 = one-fourth times 20.
Greta is correct; each person plants 4 more trees than the person before them.
Greta is correct; 4 = 4 times 1 and 20 = 4 times 5.
