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 $260 a day, at least how many hours must she work
We can make such equation which represents our problem. Assume that x is number of working hours . 42*x-75>260 42x-75>260 /+75 add 75 both sids 42x>335 /:42 divide both sides by 42 x>7,97 Adrian will stay at work at least 8 hours.
42 + 42 + 42 + 42 + 42 + 42 = 252.
Not quite there yet, and keep in mind than you need to subtract 75$ from dry cleaning.
42 x 8 = 336
Now subtract the dry cleaning expense.
336 - 75 = 261
Adrian will have to work eight hours a day to earn one dollar more than 260$.
