To calculate how much cake was left after the party, we need to subtract the amount of cake eaten from the total amount of cake.
Total cake - Cake eaten = Cake left
Let's assume the total amount of cake at the beginning was 100.
Marcie's guests ate 23, so we subtract that from the total cake:
100 - 23 = 77
Next, her family ate 14 more pieces:
77 - 14 = 63
Therefore, there were 63 pieces of cake left after her party.
At her birthday party, Marcie's guests ate 23
of her birthday cake, and her family ate 14
of the cake. How much cake was left after her party?
