A shipping container will be used to transport several 60-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24500 kilograms.

Solution

Let's start by defining the variables and the given information:

  • The maximum weight the container can hold is 24500 kilograms.
  • The weight of other shipments already loaded is 14600 kilograms.
  • Each crate weighs 60 kilograms.
  • Let x x be the number of 60-kilogram crates that can be loaded into the container.

We need to write an inequality to determine the maximum number of crates that can be added without exceeding the container's weight limit.

First, we calculate the total weight of the crates that will be added: 60x 60x

Next, we add this to the weight of the other shipments already in the container: 14600+60x 14600 + 60x

This total weight must be less than or equal to the maximum weight the container can hold: 14600+60x24500 14600 + 60x \leq 24500

Now, we solve the inequality for x x :

  1. Subtract 14600 from both sides: 60x2450014600 60x \leq 24500 - 14600

  2. Simplify the right side: 60x9900 60x \leq 9900

  3. Divide both sides by 60: x990060 x \leq \frac{9900}{60}

  4. Simplify the division: x165 x \leq 165

Therefore, the inequality that determines the number of 60-kilogram crates that can be loaded into the shipping container is: 14600+60x24500 14600 + 60x \leq 24500

And the solution to the inequality is: x165 x \leq 165

This means that up to 165 crates can be loaded into the container.

Problem Set. Three crates of Davao pomelos arrived at your warehouse. The crates are of equal sizes and properly labelled, except one:  Crate A is filled to the brim and weighs 11.25 kg; its label indicates a quantity of 20.0 pcs.  Crate B is only half-filled and weighs 6.25 kg; its label indicates a quantity of only 10.0 pcs.  Crate C weighs 9.75 kg, but has its label ripped off during transport. You need to reprint a new label and indicate the quantity of pomelos inside Crate C without actually opening the box.  What is the average weight of a Davao pomelo?  What is the tare weight of an empty crate?  How many pomelos are there in Crate C?  Can you predict how much a crate containing 30.0 pomelos would weigh?
