conversations.value: Emma and Briana invested some capital into a business. Emma's investment is supposed to yield 15% of the capital annually while Briana's should yield 10% annually. If Emma invested $300 and Briana invested $500, what will be the difference between their return-on-investment after 2 years?

conversations.value: 15% of $300 is (15/100)*$300 = $45
  Emma will earn an annual ROI of $45 for 2 years for a total of $45*2 = $90
  10% of $500 is (10/100)*$500 = $50
  Briana will earn an annual ROI of $50 for 2 years for a total of $50*2 = $100
  The difference between their ROI after 2 years is $100-$90 = $10
