Tom charges a fee of $100 a day to search for an item for the first 5 days and then $60 per day for every day after that.  How much did it cost for him to look for an item for 10 days?
The first 5 days cost 5*100=$<<5*100=500>>500
He gets 10-5=<<10-5=5>>5 days on discount
He paid 5*60=$<<5*60=300>>300 at the discounted rate
So in total he pays 500+300=$<<500+300=800>>800
#### 800
