Kris mixes plain marshmallows worth 80 cents per gram with flavored marshmallows worth 95 cents per gram to make 120 grams of marshmallows to be sold at 85 cents a gram. How many grams of flavored marshmallows does she use?
***
let x=amount of flavored marshmallows used
120-x=amount of plain marshmallows used
..
.95x+.80(120-x)=.85*120
.95x+96-.80x=102
.15x=102-96=6
x=40
amount of flavored marshmallows used=40 grams
