Can someone please help me ?

C

Step-by-step explanation:

To find percentage move the invisible decimal point at the end of the number up 2 stops so for 6% move it from 6. to 0.06 and for 15. to 0.15. Then multiply then new decimal by 34.50 to find the percentage. 6%=2.07 and 15% = 5.20. Lastly add up 34.50+2.07+5.20 to get 41.77.

*Since your book doesn't have the same answer I would go with C because it is closest to the answer that I got. I added a picture in case you are a visual learner because for me it is easier to understand things by looking at the work. Hope this helped :)*
