In this scenario:
- The independent variable (d) is the number of cake slices he sells, as this is the variable that is being manipulated or changed by Troy.
- The dependent variable (i) is the amount of money he earns, as this is the variable that depends on how many cake slices he sells.
So, the correct response is:
i = the amount of money he earns d = the number of cake slices i equals the amount of money he earns d equals the number of cake slices
