A website sells soy candles and tracks the number of cases of candles available for immediate delivery and the number of orders placed. This way, positive values represent having more candles available than orders, and negative values represent having more orders than candles available. Alisyn generates a report from the system that tracks the number of candles and the number of orders. She finds that presently there are 120 cases of candles available for immediate delivery. However, if orders for the day are just 2/5 of yesterday's orders, the company will need at least 12.8 more cases of candles than the company presently has ready to ship. What is the fewest number of cases of candles ordered from the website yesterday?
