In this scenario, the independent and dependent variables can be identified as follows:
- Independent Variable (d): the number of cake slices (this is what Troy controls or changes)
- Dependent Variable (i): the amount of money he earns (this depends on how many cake slices he sells)
So, the correct identification is:
i = the amount of money he earns
d = the number of cake slices
In summary:
i equals the amount of money he earns d equals the number of cake slices.
