m-money
c-customer order

12. more with 7
less with 2
4 times more
2 times less

13. sometimes when x=y

Answer 2

this is sometimes true I say this because if u substitute your answers that can be different or can be the same.
for ex. x=6 y=6; 6-3 and 6-3 will be the same but if x= 10 and y=15; 10-3 and 15-3 would give you different answers
