Question

The class is MATLAB and I can’t figure out the third equation to solve the system of equation. ( 3 unknowns. 3 equations) 1. A+B+C=8,500lbs 2. A($600)+B($700)+C($1,000)=$6,460,000 3.??????? Problem No. 3 (25 pts) A state has given tax breaks to a company that makes computer chips with silicon. The state has required that the company buy from the state vendors selling silicon( types of silicon; A, B, and C). The company must buy 8,500 lbs. of silicon per year; Buy at least $6,460,000 worth of silicon every year; the company must buy twice as much of Type A compared to Type B. The cost of each type of silicon is: Type A $600/lbs. Type B $700/lbs. and Type C= $1,000/lbs. Calculate how many lbs. of each silicon (A, B, & C) the company will need to buy per year. Type A = Type B = Type C =

Explanation / Answer
