Answer:
3.50
Step-by-step explanation:
First we take the 500 fee for purchasing pencils off of the total:
4700-500 = 4200
This means we pay 4200 for 1200 pencils; dividing this will tell us the amount per pencil, x:
4200/1200 = 42/12 = 21/6 = 7/2 = 3.5
Thus we pay 3.50 per pencil.
N^2 - n = 90
n^2 - n - 90 = 0
(n - 10)(n + 9) = 0
n - 10 = 0
n = 10
n + 9 = 0
n = -9
answer is : n = 10 and n = -9
