Answer:
150c + 13,700 < 23,000
Step-by-step explanation:
Greatest weight that can be loaded into the container = 23,000 kilograms
Weight of each crate = 150 kilogram
Weight of other shipment = 13,700 kilograms
c = total number of 150-kilogram crates that can be loaded
This can be represented by the inequality:
150c + 13,700 < 23,000
That is, Weight of each crate multiplied by total number of 150-kilogram crates that can be loaded Plus Weight of other shipment less than greatest weight that can be loaded into the container
