last week a producing worker had gross earnings of $390.O if she worked more than 40 hours last week and was paid 1.5 times her regular hourly rate for each hour worked in excess of 40 hours ,how many hours did she work last week?
1,If she had worked 4 more hours last week, her gross earnings would have been $435.00
2, Her regular hourly rate last week was $7.5
第一个是不是不对啊，不能确定现在1定是超过40个小时，还是没超过40个小时，还可能38+4~~~
答案是D 我觉得应该是B，大家帮帮忙啊 |
