Chris has invested $2,300 in two small businesses. last year, the greeting card business made a 14% profit on her investment in the business, while the bicycle repair business showed a 6% loss. If chris' net profit from the two businesses was $102, her investment in the greeting card business was $____?

• $ 1200
  
  If investment in a business of greeting card=x & bicycle repair=(2300-x)
  then, x*[(100+14)/100]+(2300-x)*[100-6)/100]=2300+102
  1.14x+2162-0.94x=2402, x=1200
