Resolve the problem. Justify your answer, using the formulas of both arithmetic progression and geometric progression. Jaime and Rafael are dedicated to painting houses. Jaime quotes $24 for the first hour and then adds $2.85 for each hour of work. In this way, the second hour is charged at $26.85 and so on. On the other hand, Rafael quotes $1.50 for the first hour and then doubles the cost per hour. After a 7-hour work day. What type of progression does each painter's hourly rate represent? Who would earn more, adding a total of 7 hours of work? Question solved general 11 months ago 2416
