Can you guys help me?

If myesha works overtime, she gets paid "time and a half" for every hour she works. in other words, for every hour over 40 hours myesha works each week, she gets her hourly pay plus half her hourly pay. what is myesha's pay per hour when she works overtime?

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
