Jenna starts out with 8 sapphires. She trades 3 sapphires for two rubies. If sapphires are worth $800 and rubies are worth $1200, how much money are all her jewels worth?

How many sapphires does Jenna have left? ** First find the total number of sapphires Jenna still has: 8 sapphires - 3 sapphires = <<8-3=5>>5 sapphires
How much do the sapphires cost? ** Then multiply this number by the cost per sapphire to find the total cost of the sapphires: 5 sapphires * $800/sapphire = $<<5*800=4000>>4000
How much do the rubies cost? ** Then find the total value of the rubies: 2 rubies * $1200/ruby = $<<2*1200=2400>>2400
How much do all her jewels cost? ** Then amount this to the cost of the sapphires to find the total value of her jewelry: $2400 + $4000 = $<<2400+4000=6400>>6400
