Incoming goods flow into the US at a rate of $423B/yr. Due to increased congestion, flow time has increased by one day. What is the increase in inventory on account of the one day delay? Assume the same rate of flow of $423B/yr.

My thoughts: $423B/365 days = about $1.16B/day. ($423B + $1.16B)/366 = about $1.16B. Would approximately $1.16B be correct?
