Question 1026148: If you buy a minimum of 10 sweets, you get 2 free. Which equation describe this? If I put the number I want to buy in the equation, it should tell me how many sweets I will get for free.

Let s be the number of sweets you want to buy.

If s < 10, then you get no free sweets.
If s >= 10, then you get two free sweets.

f(s) = 0 if s < 10
f(s) = 2 if s >= 10 (this should be written as a piecewise function)
