Billy Madison consumes 100 units of X and 50 units of Y. The price of x rises from 2 to 3. The price of Y remains at 4.


a/ how much must Billy’s income rise so that he can exactly afford 100 units of x and 50 units of y?


b/ Draw Billy’s original budget set when the price of X is 2


c/ Draw Billy’s budget set when the price of X is 3, but his income is unchanged


d/ Draw Billy’s budget set when the price of X is 3 and his income increases by the amount in (a) so that he can afford his original consumption bundle.

a.

income=pxx+pyyx=100,y=50px=2,py=4income=2(100)+4(50)=400income=p_xx+p_yy\\x=100,y=50\\p_x=2,p_y=4\\income=2(100)+4(50)=400

now px rises to 3 , but x=100,y=50

income=3(100)+4(50)=500income=3(100)+4(50)=500\\

income must rise by =500400=100=500-400=100


b and c

original budget 400=2x+4y400=2x+4y

x intercept =4002=200=\frac{400}{2}=200

y intercept =4004=100=\frac{400}{4}=100

new budget 400=3x+4y400=3x+4y

x intercept =4003=133.33=\frac{400}{3}=133.33

y intercept =4004=100=\frac{400}{4}=100



d.

new budget 500=3x+4y500=3x+4y

x intercept =5003=166.67=\frac{500}{3}=166.67

y intercept =5004=125=\frac{500}{4}=125
