At time t=0
a store has 19 units of a product in inventory. The cumulative number of units sold is given by S(t)=exp(3t)-1 where t is measured in weeks. The inventory will be replenished when it drops to 1 unit. The cost of carrying inventory until then is 15 per unit per week (pro-rated for a portion of a week).Calculate the inventory carrying cost that will be incurred before the inventory is replenished.請問這題的意思是在說什麼?該如何計算?
t = 0 時
商店有 19 個單位存貨
累積銷售單位以 S(t) = e^(3t)
