His utility function is given by U = VBF = B0.5 F0.5 where B is the amount of burgers he eats and F is the number of servings of fries. Find Antonio's marginal utility of a burger and his marginal utility of a serving of fries. Antonio's income is $20, and the prices of burgers and fries are $5 and $2, respectively. What are Antonio's utility-maximizing quantities of burgers and fries
