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 must work at least 8 hours in a day to make more than $260

Step-by-step explanation:

Assume that Adrian needs to work x hours in one day to make at least $260

We know that she makes $42 per hour

This means that:

If she worked x hours in a day, then she'll earn $42x

We are also given that she spends $75 daily on dry clean

This means that:

Amount she makes in a day = amount she earns - $75

Amount she makes in a day = 42x - 75

Now, she wants to make at least $260

This means that:

42x - 75 ≥ 260

42x > 260 + 75

42x > 335

x > 7.9

Therefore:

Adrian must work at least 8 hours in a day to make more than $260

Hope this helps :)
