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 25$. if she wants to make more than $260 a day, at least how many hours must she work

Answer 1

Answer:

She must work at least 7 hours

Step-by-step explanation:

Let

x ----> number of hours she has to work each day

we know that

If Adrian wants to earn more than $260 a day, then the number of hours worked per day, multiplied by $42 per hour minus $25 must be greater than $260    

The inequality that represent this situation is

$42x-25> 260$

solve for x

Adds 25 both sides

$42x> 260+25$

$42x> 285$

Divide by 42 both sides  

$x> 6.8\ h$

therefore

She must work at least 7 hours
