1. BTC uses the cost formula Y = $5,300 + $0.60X to estimate its maintenance costs where X represents machine hours. If the August budget calls for 8,000 hours of planned machine time, what maintenance cost is expected to be incurred during August?

2. MCK bases its predetermined overhead rate on the estimated machine hours for the upcoming year. Its estimates for the upcoming appear below:

Machine hours 52,800

Variable manufacturing overhead $4.10 per machine hour

Fixed manufacturing overhead $425,000

What is MCK's predetermined overhead rate based on these estimates?
