Profits Refer back to Exercise 71. It actually costs Motorel only $25 to make each processor chip, $10 for each memory chip, and $5 for each vacuum tube. It costs Intola $50 per processor chip, $10 per memory chip, and $7 per vacuum tube. Use matrix operations to find the total profit Motorel and Intola would make on each model.

Reference:

Costs Microbucks Computer Co. makes two computers, the Pomegranate II and the Pomegranate Classic. The Pom II requires 2 processor chips, 16 memory chips, and 20 vacuum tubes, while the Pom Classic requires 1 processor chip, 4 memory chips, and 40 vacuum tubes. There are two companies that can supply these parts: Motorel can supply them at $100 per processor chip, $50 per memory chip, and $10 per vacuum tube, while Intola can supply them at $150 per processor chip, $40 per memory chip, and $15 per vacuum tube. Write down all of this data in two matrices, one showing the parts required for each model computer, and the other showing the prices for each part from each supplier. Then show how matrix multiplication allows you to compute the total cost for parts for each model when parts are bought from either supplier.
