Louise cleaned for 4 and one-half hours and charged $27. At the same hourly rate, what would she charge for 6 and one-half hours of cleaning?
Please help, I forgot how to do rates.

39$

Step-by-step explanation: 4 hrs and 30 mins and you make 27$

You gotta make the hrs into minutes. So you can find the rate. 4 hrs is 240 minutes. With the 30 minutes its a total of 270 minutes. You're earning 1 dollar every 10 minutes. So i think if i did the math right 390 minutes is 6 hrs and 30 mins. And so she has earned 39$.
