There are 32 girls and 18 boys in the chorus. what percent of the students in the chorus are girls?

So the total number of students is 50, and you want to find 32/50. and that is equal to 64%

Add 32 and 18 to get 50. Then take 32/50 to get 0.64. Turn 0.64 into a percent, which would be 64%. 

64% of the students in the chorus are girls.

I hope this helps. 

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
