Answer:
1/5
Explanation:
Marginal rate of substitution (MRS) can be defined as the rate at which a consumer is willing to drop some goods in exchange for another entirely different good, but still wants to maintain the same utility level.
In this case MRS = Marginal utility of consuming an soft drink = 2
Marginal utility for consuming an extra hot dog = 10
Hence MRS (of soft drinks for hot dog) = Marginal utility of consuming an extra soft drink/Marginal utility of consuming an extra hot dog
MRS = 2/10
=1/5
