4.72n - 0.1 = 8 + 0.67n
4.72n - 0.67n = 8 + 0.1
4.05n = 8.1
4.05n/4.05 = 8.1/4.05
n = 2

(

is twice the product of 3 and x, and if it exceeds

by 10, then we add 10 to

to make the two sides of the equation equal.)
Now, solve for

.
9 and 10
11 and 12
13 and 14
15 and 16
the square root of 125 is 11.18 so therefore it falls between 11 and 12
