[tex]\\ \text{Michael distrinutes 2345 packages of screws into 5 equal groups for shipping.}\\ \\ \text{we need to find the number of packages of screws in each group.}\\ \\ \text{so for this we use the unitary method.}\\ \\ \text{The number of packages of screws in 5 groups}=2345\\ \\ \text{so the number of packages of screws in 1 group}=\frac{2345}{5}\\ \\ =469[/tex]
Hence the number of packages of screws in each shipping box is: 469
Hence option (B) is correct.
