It could happen to you

Many people think there is no need to take special care over home safety.

“I’ all right, I’m insured(投保).”

Maybe-----if you’re fully insured. Even then you can never recover the value you place upon your possessions, because you can’t insure against the suffering of mind that we all feel if our homes are torn apart by some strangers, our windows and doors broken, or our possessions ruined.

“It won’t happen to me.”

Won’t it? A house is broken into every three minutes of the day. Loss of all kinds, including cars and things stolen from cars, happens every 35 seconds.

“I’ve nothing worth stealing.”

You may think not. But in fact everyone has something worth a thief’s attention. And we all have things of personal value, even if they’re worth little or nothing inn hard cash.

“I’m only a tenant(房客) here.”

The thieves don’t care whether you’re a tenant or an owner. You’re just as weak either way. Have a word with the owner if you think extra safety fittings are necessary.

“They all get in anyway.”

Most thieves are on the lookout for easy pickings. They are soon discouraged by houses they can’t get into quickly and easily. So do pay special attention.

“This booklet(小册子) will help you…”

It’s based on the practical experience of police forces throughout the country. Most of the suggestions will cost you only a few minutes and thought. A few may cost some expense, but this is small compared with the loss and sadness you might otherwise suffer.

If you are in any doubt, ask for free advice from the crime Prevention Office at your local police station.

某企业采用标准成本法，A产品的正常生产能量为1000件，单位产品标准成本如下：

直接材料=0.1×150=15元

直接人工=5×4=20元

制造费用：

单位产品标准成本=15+20+6+5=46元

本月生产A产品800件，实际单位成本为：

直接材料=0.11×140=15.4元

直接人工=5.5×3.9=21.45元

制造费用：

单位产品实际成本=15.4+21.45+5+6.25=48.10元

要求：

采用三因素法，计算固定制造费用差异。
