Answer:
44 cakes
Step-by-step explanation:
Step one:
we are told that there are 10 friends coming,
if you are going to include yourself, a total of 11 persons in the party.
if everyone will have at least 2 of cupcakes and brownies, hence they will get 4 cakes each
Step two:
The total number of cakes you will need to get for everyone is
4*11= 44 cakes
Hence you will need 44 cakes with you inclusive
