the total contract was $2000 minus total labor cost $675  then $1325 remains to the carpenter.

For sales representative gaining income above or equal to 10000 the bonus will be 2000 and above,if income range between 8000 to 10000 the bonus will be a range of 1200 to1500,if income equal to or above 5000 the bonus will be 150 and above

Let x be the income generated.
if x>=10,000 then bonus is 2000Rs therefore the income left is 8,000.
if x>=8,000 and <10,000 then bonus is 1,200Rs therefore the income left is 6,800.
if x>=5000 then bonus is 150Rs therefore the income left is 4,850.
