Answer:
$ 20= Q1 (0.5 ) + Q3( 3)
Explanation:
Total Amount = $ 20
Dental treats Q2= $ 3
Catnip Q1= $ 0.50
Maximum no of Dental Treats he can get is = $ 20 /$3= 6.66
If he gets maximum dental treats i.e 6 , $18 will be spent (3*6)
He will be left with = $ 20- $ 18= $ 2
The maximum no of catnip he can get after buying 6 dental treats from $ 2= $ 2/$0.5= 4
Let Q1 denote the catnip and Q3 denote the dental treats then the equation would be like
$ 20= Q1 (0.5 ) + Q3( 3)
So putting the values for q1=0,1,2,3,4,5,6,7,8,9,10
for values 0-4 Q3 will be $ 18
for values 4-6 Q3 will be $ 15
for values 6-8 Q3 will be $ 12
From values Zero on wards the budget constraint will be a slope but after value 4 the change will be after every two points.
The slope will look like the one given in the diagram.
