Of the people at sunrise school, 40% are female students, 5% are staff, and the remaining people are male students. There are 270 more male students than female students. How many people are at sunrise school?

Answer: The total number of people is 1800

Step-by-step explanation:

If N is the total number of people in the school.

We know that 0.4*N = number of girls = Ng

0.05*N = staff = Ns

0.55*N = number of male students = Nm

We also know that

Ng + 270 = Nm

Now, we can wrie this as:

0.4*N + 270 = 0.55*N

And we solve it for N

270 = (0.55 - 0.4) * N = 0.15*N

N = 270/0.15 = 1800

488.7

Step-by-step explanation:

40 + 5 = 45

100 - 45 = 55

55% = 270

55 x 1.81 = 100

270 x 1.81 = 488.7 (488.7 = 100%)
