Annie has a compost pile that produces 12 pounds of compost a day from yard waste. Which function expresses the amount of compost (c) as a function of the number of days (d)? The function representing the relationship between the amount of compost and the number of days is__, with the input as__.
If it produces 12 pounds each day, for any number of days, we can just multiply by 12, correct?? So that means c=12d. Remember your input will be the days since you have to put that in the equation to calculate how much compost you have.
