To make a wordformula from the setting on the left you must find regularity!
You can see at each table there are 4 chairs. So if you know the number of tables you have to multiply by 4. But, be aware of the fixed amount! At the end there are 2 more chairs
Number of tables times 4 plus 2 is the number of chairs

And again: At this table always 6 chairs. So if you know the number of chairs you have to multiply with 6. But!!! At the end there are 2 more chairs so you must add 2 as well.
The number of tables times 6 plus 2 is the number of chairs.
Formula: number of tables x 6 + 2 = number of chairs
Fixed amount and 'per' number

It doesn't matter how many cupcakes she makes, the 12 euros is just once. The 12 euros is what we call the fixed amount
Profit = .... - number of cupcakes x .....
Slide 6 - Tekstslide
It doesn't matter how many cupcakes she makes, the 12 euros is just once. The 12 euros is what we call the fixed amount
Profit = 12 - number of cupcakes x 0,80
