To silpify the expression we proceed as follows:
(x+7)/(x^2+4x-21)
Factorizing the given the denominator:
x^2+4x-21
x^2-3x+7x-21
=x(x-3)+7(x-3)
=(x-3)(x+7)
thus plugging back in our expression we have:
(x+7)/[(x-3)(x+7)]
simplifying this we obtain:
1/(x+3)
Answer: 1/(x+3)
You would want to have more than 61% of the seats available for a smoke free area.
61% = 0.61 0.61 * 149 = 90.89 or 91 seats to accommodate 61% smoke free customers
To allow for any extra customers in a smoke free area I would figure on 65%
so 65% = 0.65 0.65 * 149 = 96.85 or 97 seats to allow for a few extra for the customers in the smoke free area
