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?
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.
