Lizzy: On a tough week, Haji's mother sells goods worth $800, which is half the amount she sells on a good week. What's the total amount of money she makes if she has 5 good weeks and 3 tough weeks?.
Me: Hmmm, let me think. I think this is the detailed solution:
If on a tough week she sells half what she sells on a good week, then on a good week she sells 800 * 2 = 1600 dollars. If she had 5 good weeks, the amount is 5 * 1600 = 8000 dollars. During the 3 tough weeks, she sells 3 * 800 = 2400 dollars. The total amount she sold in both weeks is 2400 + 8000 = 10400 dollars. Final answer: 10400.
