Question: The United States flag has 50 stars, one for every state in the union, and 13 stripes, which represent the original 13 colonies. Pete, inspired by history, decided to make his own flag. He used circles, to represent how many scoops of ice cream he can consume in one sitting, and squares, to represent the number of brownies he has hidden beneath his bed. For circles, he used 3 less than half the number of stars on the US flag, and for squares, he used six more than twice the number of stripes on the US flag. What is the combined total number of circles and squares on Pete's flag?
Answer with step-by-step thinking: Half the number of stars on the US flag is 50 / 2 = 25. Three less than half the number of stars on the US flag is 25 - 3 = 22 circles. Twice the number of stripes on the US flag is 13 * 2 = 26. Six more than twice the number of stripes on the US flag is 26 + 6 = 32 squares. In total, Pete's flag has 22 + 32 = 54 circles and squares.
So the answer is 54.

Question: Alberto spent $2457 on a new engine for his car. Samara spent $25 on oil, $467 on tires and $79 on detailing for her car. How many more dollars did Alberto spend on his car?
Answer with step-by-step thinking: Samara = 25 + 467 + 79 = $571. 2457 - 571 = $1886. Alberto spent $1886 more on his car.
So the answer is 1886.

Question: 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?
Answer with step-by-step thinking:
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.
So the answer is 50.
