Set up appropriate systems of two linear equations and solve the systems algebraically. All data are accurate to at least two significant digits.

A small isolated farm uses a windmill and a gas generator for power. During a 10-day period, they produced 3010kW · h of power, with the windmill operating at 45.0% of capacity and the generator at capacity. During the following 10-day period, they produced 2900kW · h with the windmill at 72.0% of capacity and the generator down 60 h for repairs (at capacity otherwise). What is the capacity (in kW) of each?
