Can someone please explain this to me please?
Will give brainly if you actually answer the question.

Answer: 11 is C and 12 is D.
Step-by-step explanation: On number 11, go on the calculator or just do on paper because you could put 175 over 100 then 60 over a 100 and cross multiply then divide. Once you have the answer, you have to take out the 6%. Now on number 12, an easy way to check. Is to go on Desmos. I used Desmos in 8th grade and it helped me cheat easily. :)
