Answer 1

NOT 8 CAKES

Answer 2

A.7 cakes i dont really do these right its hard for me to explain but what i do is elimination of numbers to get 91 from a multplication of 5 it would have to end in either 1 or 6 so the pies value was 56 (i got from seeing multiples of 7) then just subracted by 91 i know i dont really know how to do these but i thats how i got the answers if you do know a way would you mind showing me too?
