1. Average monthly earnings = ($150 + $300 + $180) / 3 = $630 / 3 = $210
2. Average investment = ($20,000 + $25,000 + $16,000 + $3,000) / 4 = $64,000 / 4 = $16,000
3. Average score per game = (25,000 + 125,000 + 30,000) / 3 = 180,000 / 3 = 60,000 points
4. Total pages read in 3 days = 23 * 3 = 69 pages. Pages read on Wednesday = 69 - 12 - 25 = 32 pages.
5. Total points from first 3 tests = 60 * 3 = 180 points. New total points = 180 + 100 = 280 points. New average = 280 / 4 = 70 points.
6. Total distance = (2 hours * 100 km/h) + (3 hours * 50 km/h) = 200 km + 150 km = 350 km. Total time = 2 + 3 = 5 hours. Average speed = 350 km / 5 h = 70 km/h.
