“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?

Greta’s equation is correct
As y represents the number of trees planted and x the number of people working
Method :
One person could plant 4 tree in the given time but 5 people could plant 20 trees at the same time which means 4*5 = 20
So, y = 4x is correct
