Let the number of days worked be W. The the number of day absent is
A+=+20+-+W
The pay is defined by the equation
Pay+=+120%2AW+-+10%2AA
1880+=+120W+-+10%2820-W%29
1880+=+120W+-+200+%2B+10W
1880+%2B+200+=+120W+%2B+10W
2080+=+130W
2080%2F110+=+W
16+=+W
So if they worked 16 days, they must have been absent 4
