Joelle earns her regular pay of $7.50 per hour for up to 40 hours of work in a week. for each hour over 40 hours of work in a week, joelle is paid 1 ½ times her regular pay. how much does joelle earn for a week in which she works 42 hours?

Amount of Joelle earns per hour is $7.50
Amount that Joelle earns during extra hours =1 1/2 or 7.5=3/2*7.5=11.25
thus given that she worked for 42 hours, the total amount earned will be as follows:
amount earned in regular hours=40×7.5=$300
amount earned overtime=11.25×2=22.5
Thus the total amount earned:
300+22.5
=$322.5
the total amount earned during that week is $322.5

What’s the question?
