First find the end value of Jackson's investment: $500 * 4 = $<<500*4=2000>>2000

Then find the end value of Brandon's investment: 20% * $500 = $<<20*.01*500=100>>100

Then subtract the value of Brandon's investment from the value of Jackson's investment to find the difference: $2000 - $100 = $<<2000-100=1900>>1900
