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?
If half-hour lesson is worth $10, then a one-hour lesson costs 2 * 10 = $<<10*2=20>>20.
One lesson per week would mean that in 5 weeks the teacher would earn 20 * 5 = $<<20*5=100>>100.
