Answer 2

Hey friend,
Here is the answer you were looking for:
$18(40 - f) = 704 - f \\ \\ 18 \times 40 - 18 \times f = 704 - f \\ \\ 720 - 18f = 704 - f \\ \\ - 18f + f = 704 - 720 \\ \\ - 17f = - 16 \\ \\ 17f = 16 \\ \\ f = \frac{16}{17} \\ \\ or \: in \: decimal \\ \\ f = 0.94(approx)$

Hope this helps!!!

Thanks...
