Answer:
72 Chicken Dinners and 24 Lasagna Dinners
Explanation:
Since you know that chicken dinners are 3 times as much as lasagna, you know that you must divide 96 by 4. Why? Well we aren't just looking at the chicken dinners itself. IF we were, then we would divide 96 by 3. But in this situation, you have to divide by both the lasagna and the chicken. Adding the parts together, you get 1 and 3, or 4. So, dividing 96 by 4 you get 24. You now know that the amount of lasagna dinners is 24. Chicken dinners are 3 times as much meaning 24 x 3 = 72 chicken dinners.
Algebraic expression ish (x = lasagna dinners):
96 = 3x + x
96 = 4x (divide both sides by 4 now)
24 = x
