then estimate it, you get 6000
The weight of each small tables and chairs in the United States is 15lbs and 3.5lbs respectively.
<h3>Simultaneous equation</h3>
Let
- Weight of tables = x
- Weight of chairs = y
- Cost of 3 tables and 5 chairs is 62.5lbs
- Cost of 3 tables and 2 chairs is 52lbs
3x + 5y = 62.5
3x + 2y = 52
- Subtract the equation to eliminate x
5y - 2y = 62.5 - 52
3y = 10.5
y = 10.5/3
y = 3.5 lbs
Substitute y = 3.5 into
3x + 2y = 52
3x + 2(3.5) = 52
3x + 7 = 52
3x = 52 - 7
3x = 45
x = 45/3
x = 15 lbs
Therefore, the weight of each small tables and chairs in the United States is 15lbs and 3.5lbs respectively.
