Question

A shipping container will be used to transport several 130-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 26500 kilograms. Other shipments weighing 7700 kilograms have already been loaded into the container. What is the greatest number of 130-kilogram crates that can be loaded into the shipping container?

Answer 1

c represents the number of additional crates

26500 = 7700 + 130c

Can you solve for c and answer?

Answer 2

Max. capacity is 26,500 kg., but there's already 7,700 kg loaded, so there's only 26,500 - 7,700 = 18,800 kg. available for the 130 kg crates. How many 130 kg crates are allowed? 18,800 ÷ 130 = 144.6 crates, so you'll need to round down to the nearest whole crate so as not to exceed the overall wt. limit.
