Sure! Let’s solve each word problem step by step.

Problem 1:
> A car company was trying to reduce the weight of their new electric car. The original weight was 800kg. At first, they reduced the weight by 91kg. Then, they reduced it by 84kg and another 49kg. How much does their car weigh now?
✔ Solution:
Start with original weight:
800 kg
Subtract each reduction:
- First reduction: 800 – 91 =
709 kg
- Second reduction: 709 – 84 =
625 kg
- Third reduction: 625 – 49 =
576 kg
✔ Answer: 576 kg
*(You can also add all reductions first: 91 + 84 + 49 = 224 kg, then subtract from 800: 800 – 224 = 576 kg)*

Problem 2:
> Michael lost weight over 5 months. He weighed 141kg in the beginning. He lost 19kg the first month, 9kg the second, 13kg the third, 21kg the fourth and 15kg the fifth month. How much does he weigh now?
✔ Solution:
Start with original weight:
141 kg
Add up total weight lost:
19 + 9 + 13 + 21 + 15 =
→ 19 + 9 = 28
→ 28 + 13 = 41
→ 41 + 21 = 62
→ 62 + 15 =
77 kg lost
Now subtract from original weight:
141 – 77 =
64 kg
✔ Answer: 64 kg
