Please Explain step-by-step An algebra class contains 30 students. Forty
percent of the students in the class are girls. How
many boys are in the class?

So the 30 students as a percent would be 100, so when solving this problem you would put the 40 over the 100. Now you have to multiply 30 times 40 and divide by a 100, which would equal 12. 12 is how many girls there is so now you have to subtract 30 and 12 which would equal 18. Theres 18 boys in the class.

It is 198,87032,750 + 375 = 33145 so, we take the 6% and we make it a decimal (0.6) and multiply that, then that is your answer
