As a graduate student, Ed has a fixed food budget and consumes only two items: ramen noodles and pizza. Given his current consumption levels, Ed’s marginal utility for a package of ramen noodles is 50 utils, while his marginal utility for a slice of pizza is 150 utils. The price of a package of ramen noodles is $0.25 and the price of a slice of pizza is $1.50. How can Ed increase his total utility and reach a higher indifference curve? Explain your reasoning
According to utility maximizing condition a consumer should choose than quantity of X and Y such that MUp/Pp = MUn/Pn
where MU represents Marginal utility and P represents price
Here Let Pizza be denoted by p and Ramen Noodles by n.
according to utility maximizing condition: MUp/Pp = MUn/Pn
Here MUp = 150 , Pp = 1.5 , MUn = 50 Pn = 0.25
Here MUp/Pp = 150/1.5 = 100
and MUn/Pn = 50/0.25 = 200
=> MUn/Pn > MUp/Pp
Hence In order to equalize this MUn/Pn should decrease and MUp/Pp should increase.
According to law of diminishing marginal utility , Marginal Utility of good X decreases as we increase the consumption of Good X.
Hence, In order to MUn/Pn to decrease we have to increase the consumption of Ramen Noodles and MUp/Pp to increase we have to decrease consumption of Pizza.
Hence, Ed can increase his total utility and reach a higher indifference curve If he increases consumption of Ramen Noodles and decrease consumption of Pizza.
