First, start by multiplying 6.50 by 40, to get your straight time. The product is 260. The add that to the overtime. Getting the overtime is a bit more complicated. Start with multiplying 6.50 by 1.5, which gives you 9.75. Then multiply that by the 5 hours worked overtime, to give you 48.75. Finally, add 260 (from the beginning) to the 48.75 we just found. Your answer should be, "She earned $308.75 last week."
