What to Focus On
- x, y, z are the numbers of units of P1, P2, P3.
- Three equations come from the three raw materials.
- The solution is x = 20, y = 35, z = 5.
- x = bottles of M1, y = bottles of M2.
- Objective function: Z = 8x + 7y.
- All five constraints are needed.
- x is the independent variable.
- C, I and P are dependent variables.
- a, b and s are parameters.
Common Mistakes to Avoid
The height of a tower is just h + l, so the angle can be ignored once the eye height and horizontal distance are known.
When the foot of the tower is inaccessible, the distance l can still be found by using l = h tanβ.
The five-step modelling process must always be completed fully, even when the data are already exact.
