Alaina’s sugar cookie recipe calls for 2 1/4
cups of flour per batch. if she wants to make 2/3
a batch of cookies, how much flour should she use?
a) 2/9 cups
b) 1 1/2 cups
c) 2 1/6 cups
d)3 3/8 cups

the answer is b. it is not d.

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.

1.35x+1.08y=104.49.

3. solve the system of two equations:
