Bob is having a party and wants to order some cakes.

there will be 57 guests and he wants to make sure everyone gets a slice of cake.
he wants to pay as little as possible for the cakes and for them to be the same size.

how much will he have to pay for the cakes?

There isn't a possible way you can really answer this question because I don't know how much one piece cost in the first place , but if I had to guess I would say around 50-80 dollars for a cake is enough for 57 guests.

explanation: I say this because I know usually cakes for a decent amount of people are around 50-80 dollars.
