Plugging in 164 gives us 164 = 4s, where solving for s gives us s = 41
The total loss of the two months would be $72.
From 10 to 15 -> 10 increased with half its size (5), that means increase of 50%
From 16 to 12 -> decrease of 4, which is a quarter of 16, that means a decrease of 25%
50$ on Saturday - $12.50 x 4hrs = $50
58$ on Sunday - $14.50 x 4hrs = $58
