A container has 80 liters of a solution that is 25% salt. How much salt is in the container?

A container has 80 liters of a solution that is 25% salt. How much salt is in the container?

Step 1: Understand that the solution is 25% salt. This means that for every 100 liters of solution, there are 25 liters of salt.
Step 2: We have a total of 80 liters of solution.
Step 3: To find out how much salt is in the 80 liters, we need to calculate 25% of 80 liters.
Step 4: Convert 25% to a decimal. 25% as a decimal is 0.25.
Step 5: Multiply the total volume of the solution (80 liters) by the decimal (0.25).
Step 6: Calculate 0.25 * 80 = 20 liters.
Step 7: Conclude that there are 20 liters of salt in the container.
