The clown cost 100*4=$<<100*4=400>>400

The bounce house cost 100*3=$<<100*3=300>>300 per hour

He rented it for 4/2=<<4/2=2>>2 hours

So it cost 300*2=$<<300*2=600>>600

That means the total cost was 400+600+1000=$<<400+600+1000=2000>>2000

Tim had a birthday party with a clown that cost $100 an hour for 4 hours.  He also rented a bounce house for half the time that cost 3 times as much an hour. Everything else for the party cost $1000.  How much did his birthday cost?
