Question 328371: A rice dealer mixes two varieties of rice, one that sells at P500 a sack and anotherat P520 a sack. He intends to fill up 100 sacks to be sold at P515 each. How many sacks of rice each variety are needed? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let the number of P500 sacks he mixes be x
the P520 he mixes will be 100-x
..
mixture P515 100 bags
500x+520(100-x)=515*100
500x+52000-520x=51500
-20x=51500-52000
-20x=-500
x=-500/-20
x=25 -------- the p500 type
balance 75 will be P520 type sacks
