2nd: we make an example of a linear formula:
- Suppose we, as a class and a teacher, go on a rowing trip on the
- The fixed amount (the money we have to pay, no matter how many boats are hired) is 15 euros.
- The number of boats we hire we call b.
- Every boat costs 5 euros.
- The total cost for the trip we call c.
- In the next slide CHOOSE the RIGHT FORMULA for this trip.
