We have that
[(4x+2)/(x+5)]-[(3x+1)/(x+5)]
<span>They have common denominators, so just add the numerators like normal fractions:</span>
=[(4x+2)-(3x+1)]/(x+5)
=[(4x+2-3x-1)]/(x+5)
=[(x+1)]/(x+5)
the answer is
(x+1)/(x+5)
5/7 + 5/14 = 1.07142857143
you can round that to 1.1
10 n = C
Finding the total would simply be multiplying the cost of the tickets by number of students.
