When you multiply a number by a percentage, you first convert the percent into a decimal.
You do this by moving the decimal point two places to the left and making the decimal point into % sign.
15% = 0.15
Then you multiply the decimal by the number you want to find the percentage of.

Answer:
C.47
Step-by-step explanation:
You want to plug in all the numbers which gives you 3^3+2(8)- -4. You do 3*3*3 which gives you 27. You then do 2(8) which gives you 16. So your problem now is 27+16- -4. 27+16 is 43 and being you are subtracting a negative, it turns to a positive. So your answer ends up being 47.
Actually, it is 16, not 26. I took the test twice because I missed this question. Apex.
