Marilyn wants to buy a pair of boots online. On Amazon.com, the boots cost $16 and shipping costs $4. On eBay, those same pair of shoes are only $13, but shipping costs twice as much as it does on Amazon. How much more expensive do the boots work out to be on eBay?

How much does the total cost on Amazon.com end up being? ** The total cost on Amazon.com is $16 + $4 = $<<16+4=20>>20
How much does shipping on eBay cost? ** Shipping on eBay costs $4 x 2 = $<<4*2=8>>8
How much does the total cost on eBay end up being? ** The total cost on eBay is $13 + $8 = $<<13+8=21>>21
How much more expensive do the boots work out to be on eBay? ** The boots cost $21 - $20 = $<<21-20=1>>1 more on eBay
