He needs to buy 60*.6=<<60*.6=36>>36 pounds

So he needs to buy 36/2=<<36/2=18>>18 weight plates

That would cost 18*5=$<<18*5=90>>90

Since he bought more than 10 he gets a discount so he gets 90*.2=$<<90*.2=18>>18 off.

That means he paid 90-18=$<<90-18=72>>72

Thomas buys a weight vest.  It weighed 60 pounds and worked well for him in the beginning but after a bit of training he decides he wants to increase the weight by 60%.  The weights come in 2-pound steel ingots.  Each ingot cost $5 and if you buy more than 10 you get a 20% discount.  How much does it cost to get the weight he needs?
