Miriam consumes tacos and coke. suppose the price of a taco is $3.80, the price of a coke is $2.70, and that miriam is currently consuming tacos and coke such that her marginal utility of tacos is 87 and her marginal utility of coke is 45. is miriam behaving optimally? if not, then what should she do?

answer: t=3

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the correct answer is x/3+10≥32

hope this !
