Answer:
Toby is not maximizing his utility because MUp/Pp > MUc/Pc
Explanation:
given data
marginal utility consuming peanuts = 100 utils per ounce
marginal utility consuming cashews = 200 utils per ounce
peanuts cost = 10 cents per ounce
cashews cost = 25 cents per ounce
solution
we know that Toby will have maximize utility when here
Marginal utility of peanut ÷ price of peanut = Marginal utility of cashew ÷ cash ..........................1
MU (p) ÷ P (p) = MU (c) ÷ P (c)
put here value
but here
10 > 8
so we can say Toby is not maximizing his utility because MUp/Pp > MUc/Pc
