Imagine that Sarah has a choice between two productive activities:fixing sprinklers or planting trees.It takes her 1 hour to fix a sprinkler and 2hours to plant a tree.Assuming that fixing sprinklers is on the x-axis and planting trees is on the y-axis, what is the equation for Sarah's PPF if she works for 10 hours?

y=5-0.5x

y=10-2x

y=2-x

y=10-0.5x
