im not very good at math in general

Answer 1

In 10 hours he can do 5x2 hours work. or 5x$50 = $250 for 5 rooms

$150 is 3x $50 or 3x2 hours work.

He can work 6 hours and make $150

or he can work 10 hours and make $250

the range he can earn so that he makes at least $150 and no more than 10 hours is

$150 to $250

($150,$250) in interval notation for working 6 to 10 hours (6,10)
