Correct Answer:
B
Suppose a consumer has an income I = $50 which he/she spends on pizza and tacos per month.The price of pizza is $10 and the price of tacos is $5.If the units of pizza consumed per month is on the x-axis and the units of tacos consumed per month is on the y-axis,the slope of the budget line is equal to

Correct Answer:
C
Let I be the income of the consumer,Px be the price of good x and Py be the price of good y.If good
is measured along the horizontal axis and good
is measured along the vertical axis,then the "
-intercept" measures the maximum amount of good
that the consumer can afford,which can be expressed as
