Question

Adrian works in New York City and makes $42 per hour. she works in an office and must get her suit dry cleaned everyday for $75. if she wants to make more than $260 a day , at least how many hours must she work?

Answer 1

Adrian will need to work 8 hours a day

Answer 2

We can make such equation which represents our problem.
Assume that x is number of working hours .
42*x-75>260
42x-75>260 /+75 add 75 both sids
42x>335 /:42 divide both sides by 42
x>7,97
Adrian will stay at work at least 8 hours.
