What is the dependent and independent variable in this problem? Lots of points to win!?

Hi

Please help me with finding both the independent and dependent variable in the following problem:

A landscape supply business charges $30 to deliver mulch. The mulch costs $23 per cubic yard.

Thanks and lots of points to win!!!!What is the dependent and independent variable in this problem? Lots of points to win!?
The cost for mulch in dollars is:



鈥冣€冣€冣€僀 = (23鈥夆€⑩€塚) + 30鈥?..鈥僫f it is delivered



鈥冣€冣€僡nd鈥冣€侰 = 23鈥夆€⑩€塚鈥?..鈥僫f it is not delivered



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~鈥?br>


Regardless of whether it is delivered or not:



鈥僔 = independent variable = volume of mulch ordered

鈥僀 = dependent variable = cost



Technically, whether one chooses to have it delivered is also an independent variable

since the Cost is dependent on that decision also.



鈥冣€僆ndependent: The volume ordered and the delivery option chosen.



鈥冣€僁ependent: CostWhat is the dependent and independent variable in this problem? Lots of points to win!?
Both Are Independent Variables Because Buisiness Charges Are No Where Related To Mulch Cost Irrespective Of Mulch Cost The Buisiness Charges Were 30$ For Delevering The Mulch And In The Similar Way Mulch Cost 23$ per Cubic Yard Which Itself Is An Independent Variable As Its Not Depending On Any Other ConstraintWhat is the dependent and independent variable in this problem?

independent: mulch

dependent: cost of mulch



The cost of mulch DEPENDS on how much mulch is bought
