Caprice is taking piano lessons. Her mother pays the teacher $10 for every half-hour of teaching her daughter. If Caprice is taking one lesson per week, and the lesson lasts 1 hour, how much money would the teacher earn in 5 weeks? Let's be accurate as possible.
If half - hour lesson is worth $10, then a one - hour lesson costs 2 * 10 = $20. One lesson per week would mean that in 5 weeks the teacher would earn 20 * 5 = $100.
The answer: 100.
