A baker melts 80 grams of chocolate that contains 40% cocoa and mixes it with 60grams of his secret mixture. The result is a chocolate with 55% cocoa. What is the percent of cocoa in the baker's secret mixture?

ingredients in = ingredients out

.4 (80)   +  x (60) =  .55 (80+60)

x= .75     or 75%
