Solving Systems with Gaussian Elimination · Exercise 62
Set up the augmented matrix that describes the situation, and solve for the desired solution.
A bag of mixed nuts contains cashews, pistachios, and almonds. There are 1,000 total nuts in the bag, and there are 100 less almonds than pistachios. The cashews weigh 3 g, pistachios weigh 4 g, and almonds weigh 5 g. If the bag weighs 3.7 kg, find out how many of each type of nut is in the bag.
