### Instruction:
Monica made cookies for herself and her family. Her father ate 10 cookies and her mother ate half as much as the father. Her brother ate 2 more than her mother. How many cookies are left for Monica if she made 30 cookies in total?

### Response:
 Mama yake Monica alikula nusu ya mikate kama baba yake Monica, ambayo ni 10/2 = <<10/2=5>>5 mikate.
Ndugu yake Monica alikula 5+2 = <<5+2=7>>7 mikate.
Kulikuwa na 30-10-5-7 = <<30-10-5-7=8>>8 mikate iliyobaki kwa Monica.
