I'll solve each problem step by step, checking my calculations carefully.
Problem 1:
Original weight: 800 kg
First reduction: 91 kg
Second reduction: 84 kg
Third reduction: 49 kg
Total reduction = 91 + 84 + 49 = 224 kg
New weight = 800 - 224 = 576 kg
Let me verify: 800 - 91 = 709, then 709 - 84 = 625, then 625 - 49 = 576 ✓
Problem 2:
Starting weight: 141 kg
Month 1 loss: 19 kg
Month 2 loss: 9 kg
Month 3 loss: 13 kg
Month 4 loss: 21 kg
Month 5 loss: 15 kg
Total weight lost = 19 + 9 + 13 + 21 + 15 = 77 kg
Current weight = 141 - 77 = 64 kg
Let me verify: 141 - 19 = 122, 122 - 9 = 113, 113 - 13 = 100, 100 - 21 = 79, 79 - 15 = 64 ✓
Problem 3:
Previous hours: 185 hours/month
Works 112 hours less than before
Current hours = 185 - 112 = 73 hours/month
Let me verify: 185 - 112 = 73 ✓
Problem 4:
April earnings: $992
May earnings: $365
Difference = 992 - 365 = $627
Let me verify: 992 - 365 = 627 ✓
Final Answer:
1. 576 kg
2. 64 kg
3. 73 hours
4. $627
