Lizzy: One kilogram of tomatoes is 20% cheaper than one kilogram of cucumbers. One kilogram of cucumbers costs $5. What is the price of two kilograms of tomatoes and three kilograms of cucumbers?.
Me: Hmmm, let me think. I think this is the detailed solution:
One kilogram of tomatoes is 20 / 100 * 5 = $1 cheaper than one kilogram of cucumbers. This means that one kilogram of tomatoes costs 5 - 1 = $4. So two kilograms of tomatoes is a cost of 2 * 4 = $8. And three kilograms of cucumbers is a cost of 3 * 5 = $15. So the price for both products would be 8 + 15 = $23. Final answer: 23.
