Bella eats 6 apples a day. If during the week she consumes a third of the apples Grace picks, how many apples will Grace have after 6 weeks? Give the rationale and then the answer.
Let's think step by step. Bella eats during the week, 6 apples / day * 7 days / week = 42 apples / week. Grace harvests 42 apples / week * 3 = 126 apples during the week. Leftover after Bella eats, 126 apples / week - 42 apples / week = 84 apples / week. After 6 weeks Grace will have 84 apples / week * 6 weeks = 504 apples.. The answer is: 504.

A car manufacturing company that produces 100 cars per month wants to increase its production to reach 1800 cars per year. How many cars should the company add to the monthly production rate to reach that target? Give the rationale and then the answer.
Let's think step by step. Let Y be the number of cars needed to be added to the current monthly production. Then ((100 + Y) * 12) = 1800. So 1200 + 12 * Y = 1800. 12 * Y = 1800 - 1200 = 600. Y = 600 / 12 = 50.. The answer is: 50.

To make fried green tomatoes, Thelma cuts each green tomato into 8 slices before cooking them up. If 20 slices of fried green tomato make a meal for a single person, how many tomatoes will Thelma need to make enough fried green tomatoes to feed a family of 8 for a single meal? Give the rationale and then the answer.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Let's think step by step. If 20 slices are sufficient for a meal to feed a single person, then to feed eight Thelma will need 8 * 20 = 160 slices of tomato. At 8 slices per tomato, Thelma will need 160 / 8 = 20 tomatoes to feed a family of 8.. The answer is: 20.
