Question

1. comparative and absolute advantage activity frame kai and jalen are farmers. each one owns an 18 - acre plot of land. the following table shows the amount of kale and celery each farmer can produce per year on a given acre. each farmer chooses whether to devote all acres to producing kale or celery or to produce kale on some of the land and celery on the rest.

	kale (pounds per acre)	celery (pounds per acre)
jalen	18	6

on the following graph, use the blue line (circle symbol) to plot kai’s production possibilities frontier (ppf), and use the purple line (diamond symbol) to plot jalen’s ppf.
(graph: vertical axis is celery (pounds) with values 0, 18, 36, 54, 72, 90, 108, 126, 144, 162, 180; horizontal axis is kale (pounds) with values 0, 90, 180, 270, 360, 450, 540, 630, 720, 810, 900. there are two lines: blue line labeled kai’s ppf, purple line labeled jalen’s ppf)

Explanation:

Step1: Calculate Kai's max kale

Total kale = 28 lbs/acre × 18 acres
$\text{Max Kale (Kai)} = 28 \times 18 = 504$ pounds

Step2: Calculate Kai's max celery

Total celery = 7 lbs/acre × 18 acres
$\text{Max Celery (Kai)} = 7 \times 18 = 126$ pounds

Step3: Calculate Jalen's max kale

Total kale = 18 lbs/acre × 18 acres
$\text{Max Kale (Jalen)} = 18 \times 18 = 324$ pounds

Step4: Calculate Jalen's max celery

Total celery = 6 lbs/acre × 18 acres
$\text{Max Celery (Jalen)} = 6 \times 18 = 108$ pounds

Step5: Define PPF endpoints

Each PPF is a straight line connecting two points: (max kale, 0) and (0, max celery)

Answer:

For Kai's PPF (blue circle line):

• Plot the point $(504, 0)$ (all land for kale)
• Plot the point $(0, 126)$ (all land for celery)
• Draw a straight line connecting these two points

For Jalen's PPF (purple diamond line):

• Plot the point $(324, 0)$ (all land for kale)
• Plot the point $(0, 108)$ (all land for celery)
• Draw a straight line connecting these two points
