Total utility = 45; Marginal Utility = 5 O b. Total utility = 50 ; Marginal Utility = 10 O c. Total utility = 45; Marginal Utility = 10 O d.
Ifthe utility function of an individual takes the form U=U(x 1,x 2 )=(x 1 +2 ) 2 (x 2 +3) 3. Where U is total utility, and x 1 and x 2 are the quantities of two commodities consumed: i. Find the marginal utility function of each of the two commodities. ii. Find the value of the marginal utility of the first commodity when 3 units of eachcommodity are consumed. Marginalutility may be decreasing when more units are consumed but as long as marginal utility is positive total utility will increase when another unit is consumed. The law of diminishing marginal utility states that the: marginal utility associated with the consumption of a good or service becomes smaller with each extra unit that is consumed in a given time period. . 478 210 492 272 70 436 375 172
