**Weegy:** At the beginning of the first day, a company has 64 shipping crates on backorder. By the end of each day, customers order 18 more shipping crates. [ If the company employees work overtime and make 28 shipping crates every day, 14 crates will be on backorder at the beginning of the fifth day.
Solution:
64 + 18x
64 + 18x - 28x
64 - 10x
For day 5, we substitute the value of x with 5:
64 - 10(5) = 64 - 50 = 14 ]
