Question: A farmer planted 30 rows of tomatoes with 10 plants in each row. Each tomato plant yields 20 pieces of tomatoes. How many pieces of tomatoes can the farmer get from all his planted tomatoes?
Answer with step-by-step thinking: The farmer planted a total of 30 x 10 = 300 tomato plants. Thus, the farmer can get 300 x 20 = 6000 pieces of tomatoes.
So the answer is 6000.


Question: John has 3 bedroom doors and two outside doors to replace. The outside doors cost $20 each to replace and the bedroom doors are half that cost. How much does he pay in total?
Answer with step-by-step thinking: The outside doors cost 2 * $20 = $40. Each indoor door cost $20 / 2 = $10. So all the indoor doors cost $10 * 3 = $30. That means the total cost is $40 + $30 = $70.
So the answer is 70.


Question: Gargamel needed new tires for his truck. He went to the auto shop and bought 4 tires on sale for $75 each. The salesman told him that he saved a total of $36. If Gargamel saved the same amount on each tire, what was the original price of each tire?
Answer with step-by-step thinking:
Gargamel saved $36 for all four tires, so to find the savings per tire was $36 / 4 = $9 saved per tire. Adding the savings to the discount price, the original price was $75 + $9 = $84.
So the answer is 84.
