Final answer:
To find the amount of cake remaining after serving a certain number of guests, subtract the number of guests served from the total volume of the cake.
Step-by-step explanation:
To find out how much cake is remaining after serving a certain number of guests, we can subtract the amount of cake served from the total volume of the cake. The expression given in the question models the amount of cake remaining after serving g guests, and the volume of the cake is 468 cubic inches. To find the amount of cake remaining after serving 50 guests, we substitute g = 50 into the expression and solve for the remaining cake.
Expression: remaining_cake = 468 - g
Substituting g = 50:
remaining_cake = 468 - 50 = 418 cubic inches
