Possibility	Grade in Math 101( %)	Skiing(Days per month)
A	57	8
b	77	6
C	82	4
D	85	2
	87	0

A 57 8

B 77 6

C 82 4

D 85 2

E 87 0

C. Draw the PPF precisely

Answer 1

a. 2 to 4 days a month

Opportunity cost= Change in possibility grade/ Change in skiing day=(85-82)/(2-4)= -1.5%

When she increases her number of days spend skiing from 2 to 4, the percentage grade in maths decreases by 1.5%.

b. 4 to 6 days a month

Opportunity cost= Change in possibility grade/ Change in skiing day=(82-77)/(4-6)= -2.5%

When she increases her number of days spend skiing from 2 to 4, the percentage grade in maths decreases by 2.5%.
