Answer 3

Problem:

To solve this problem, we need to find the total mass of the detergent purchased. We are given that 4 packages of hand washing detergent were bought, each weighing 3 kg, and the same number of machine washing detergent packages were bought, each weighing 5 kg. We need to determine the total mass of the detergent.

Solution:

To find the total mass of the detergent, we can multiply the number of packages by the mass of each package and then add the results for hand washing and machine washing detergents.

Let's calculate the total mass step by step:

1. Mass of each hand washing detergent package: 3 kg. 2. Number of hand washing detergent packages bought: 4. 3. Total mass of hand washing detergent: 3 kg/package * 4 packages = 12 kg.

4. Mass of each machine washing detergent package: 5 kg. 5. Number of machine washing detergent packages bought: 4. 6. Total mass of machine washing detergent: 5 kg/package * 4 packages = 20 kg.

7. Total mass of both hand washing and machine washing detergents: 12 kg (hand washing) + 20 kg (machine washing) = 32 kg.

Therefore, the total mass of the detergent purchased is 32 kg.
