Profit Percentage = 20%. Profit = 20% of $50 = 0.2 * $50 = $10. Selling Price = Cost Price + Profit = $50 + $10 = $60. Therefore, the selling price is $60.

Riverdale Learning Institute answered |
Discount = Marked Price - Selling Price = $500 - $400 = $100. Discount Percentage = (Discount / Marked Price) * 100% = (100 / 500) * 100% = 20%. Therefore, the discount percentage is 20%.

Academia Elite answered |
Total weight of 5 students = 5 * 60 = 300 kg. Total weight of 3 additional students = 3 * 70 = 210 kg. Total weight of all 8 students = 300 + 210 = 510 kg. New average weight = Total weight / Total number of students = 510 / 8 = 64 kg. Therefore, the new average weight of all 8 students is 64 kg.
