Depending on how it is written, it could be either of these following solutions:
f(x) = x/2 - 6 or f(x) = x/(2-6)
For the first, we solve for x by replacing f(x) with 0
x/2 - 6 = 0
x/2 = 6
x = 3
For the second, do the same
x/(2-6) = 0
x/-4 = 0
x = 0
Answer:
520
Step-by-step explanation:
Past number of pupils: p
Increase of 57% = 1.57
Present number of pupils = 817
p x 1.57 = 817
p = 817 divided by 1.57 = 520.382
rounded to the nearest whole number = 520 (this is why the question says "about" how many...)
