SUMMARY
To calculate the mixture of iodine solutions, Sarah needs to combine 20% iodine and 70% iodine solutions to achieve a final concentration of 57.5% iodine in a total volume of 400 liters. The method of alligation is recommended for solving this concentration problem efficiently. By applying this technique, Sarah can determine the exact volumes of each solution required to meet her target concentration.
