Solving Systems with Inverses · Exercise 63
Write a system of equations that represents the situation. Then, solve the system using the inverse of a matrix.
A farmer constructed a chicken coop out of chicken wire, wood, and plywood. The chicken wire cost $2 per square foot, the wood $10 per square foot, and the plywood $5 per square foot. The farmer spent a total of $51, and the total amount of materials used was He used more chicken wire than plywood. How much of each material in did the farmer use?
