Answer:
You need 5 times each one for 120 servings. (120/24 = 5)
So 5 × Half cup butter = 2 and 1/2 cups of butter for 120 servings
And 5 × 1/3 cup sugar = 1 and 2/3 cups of sugar for 120 servings
And 5 × 1/2 cup light sugar = 2 and 1/2 cups of light sugar for 120 servings
And 5 × 1 egg = 5 large eggs for 120 servings
5 × 1 TSP vanilla extract = 5 TSP vanilla extract
5 × 1/2 TSP baking powder = 2 and 1/2 TSP baking powder
5 × 1 and 1/2 cups of flour = 7 and 1/2 cups of flour for 120 servings
5 × 1 and 1/2 cups of choc chips = 7 and 1/2 cups of choc chips for 120 servings
3) 4 more eggs (5-1)
4) 2 and 1/2 times - 60 ÷ 24 = 2.5
Hope this helps!!!
