The card states that it serves 20 people. What will need to be done to make enough to serve 30 people? Show your work neatly and then rewrite a recipe card.
1/2 c. butter
1 1/3 c. sugar
1/4 tsp baking soda
1 egg
1/2 tbsp vanilla
1 1/2 c flour

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
