30 * 40 + 45(h - 40)

let me try to explain this...
the 30 * 40 is saying that she normally gets paid $ 30 per hr for 40 hrs
the (h - 40) is the number of hrs after 40 hrs
the 45 is saying that for any hrs after 40 hrs, she gets paid $ 45 per hr

so ur answer is : B. the number of dollars per hr she got paid for all hrs over 40.
