John works at a nutrition supplement store. Every month, he has a quota of tubs to reach in sales. The amount of tubs he still has to sell by the end of each month can be approximated by the equation T = 500 - 20D, where T is the number of tubs left to be sold and D is the number of days he has worked that month. What is the meaning of the value of 500 in this given equation?
John is expected to sell 500 tubs per month.
