Answer:
B. equals the relative price of the two goods.
Step-by-step explanation:
A budget constraint refers to how much money a person or a company has to spend in any given pair of goods or services, e.g. you have $10 and you want to eat hot dogs and drink Coke.
The slope of the budget constraint refers to the relative price of the two goods or services, e.g. a hot dogs costs $2 and a Coke costs $1.50. The slope of the budget constraint = $1.50 / $2 = 0.75. The slope of a budget constraint is always equal or less than 1, that is why the smallest value is the numerator.
