Answer:
14 days
Step-by-step explanation:
Amount earned by gardener for each day worked = $60
Amount paid by gardener for each day when absent = $15
Total number of days = 20
Let the total number of days when the gardener was working = x
Then he was absent for (20 - x) days.
Total amount earned during this period = $750
Then, [tex]\[60x - 15(20-x) = 750\] [/tex]
=> [tex]\[60x + 15x - 300 = 750\][/tex]
=> \[75x = 1050\]
=> x = 14
So the gardener worked for 14 days out of 20.
