Answer-
About 15 shipments are shipped late per day.
Solution-
A shipping department ships 500 boxes per day on average,
Approximately 97% of those shipments are shipped on time and the remaining 3% are shipped late.
Number of shipments shipped on time is,
![=500* (97)/(100) =485](https://img.qammunity.org/2019/formulas/mathematics/middle-school/histmr2todplpeklq75atuhq0ribslxbsf.png)
Number of shipments shipped late is,
![=500* (3)/(100) =15](https://img.qammunity.org/2019/formulas/mathematics/middle-school/k2p2lwbqjcpz8ytndk21ulado9eb47xon7.png)
Therefore, 15 shipments are shipped late per day.
