<human>:  This year the Oscar swag bags include two diamond earrings that cost $6,000 each, a new iPhone that costs $2,000, and some designer scarves that each cost $1,500. If the total value of the swag bag is $20,000, how many scarves are there?
<bot>: How much do the diamond earrings cost? ** First find the total cost of the diamond earrings: $6,000/earring * 2 earrings = $<<6000*2=12000>>12,000
How much do the scarves cost? ** Then subtract the cost of the earrings and iPhone from the total cost of the bags to find the cost of all the scarves: $20,000 - $12,000 - $2,000 = $<<20000-12000-2000=6000>>6,000
How many scarves are there? ** Then divide the total cost of the scarves by the cost per scarf to find the number of scarves: $6,000 / $1,500/scarf = <<6000/1500=4>>4 scarves
