Question： 

A consumer has a budget of $30 per month to spend on two types of fruit, priced as follows: 
• Apples: $2.50 per pound.
• Bananas: $2.00 per pound.
Assuming the quantity of apples is measured on the vertical axis and bananas on the horizontal axis, the slope of the budget constraint is closest to: 
A. 1.25.
B. –0.80. 
C. –1.25.  

Answer = B 
The budget constraint is given by the formula: 2.5 QA + 2.0 QB = 30, where QA and QB are quantities ofapples and bananas purchased, respectively. With the quantity of apples measured on the vertical axis, the slope is equal to –(PB/PA) = –(2.00/2.50) = – 0.8, where PA and PB are prices ofapples and bananas, respectively.
