$\frac{a}{x+a} + \frac{b}{x-b} = \frac{a+b}{x+c}\\\frac{a(x-b) + b(x+a)}{(x+a)(x-b)} = \frac{a+b}{x+c} \\\frac{x(a+b)}{(x+a)(x+b)} = \frac{a+b}{x+c}\\x(x+c) - (x+a)(x+b) = 0\\x(c -b -a) = ab\\x = \frac{ab}{c-b-a}$

LiRa [457]

Well it's giving you what the cost is (42.3), so plug that in for $c$ :

$42.3 = 9.8v + 22.7$

And now you need to solve for the number of visits ( $v$ )!

$19.6 = 9.8v$

$v=2$

So you can visit the museum a maximum of 2 times!
