Unit 8: Systems of Linear Equations Final Review Assignment 9. A factory is currently running at 85% of its original capacity, and management is considering upgrading the equipment. The upgrade will take 6 months, during which time the factory will not run at all. Once complete, the factory's output will increase to 120% of the original capacity. After how long would the upgraded factory's production match the current 85% production? In other words, how long will it take for the factory to make up for the loss of 6 months? (Hint: The problem can be solved using a system of equations, but any method is acceptable as long as it is justified. If you get stuck, try letting the factory's original output be 100 units per month.)
