If the experienced sailors received 1/5 times more money than the inexperienced sailors, they were paid 1/5*10 = $<<1/5*10=2>>2 more.
The total hourly earnings for the experienced sailors each is $10+$2= $<<10+2=12>>12
In a 60-hour workweek, an experienced sailor is paid 60*$12 = $<<60*12=720>>720
In a month, an experienced sailor is paid 4*$720 = $<<4*720=2880>>2880
If there were five inexperienced sailors, the total number of experienced sailors was 17-5 = 12
If each experienced sailor was paid $2280 per month, the total combined monthly earnings for the experienced is 12*2880 = $<<12*2880=34560>>34560
