Question 1009963: How many grams of brand A coffee worth P4.00 gram must be added to 100 grams of brand B coffee worth P 7.00 per gram to produce a mixture worth P6.00 per gram? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call the number of grams of coffee A, x. The set up is like this
4x + 7(100) = 6(x + 100)
4x + 700 = 6x + 600
100 = 2x
x = 50 grams
