Question: Sally earned $1000 at work last month. This month, she received a 10% raise. How much money will she make in total for the two months?
Answer with step-by-step thinking: This month she will earn $1000 * (110 / 100) = $1100. In total, she will make $1000 + $1100 = $2100.
So the answer is 2100.


Question: Jason is planning a parking garage that will have 12 floors. Every 3rd floor has a gate where drivers have to show ID, which takes two minutes. To get from one floor to the next, drivers have to drive 800 feet at 10 feet/second. How long, in seconds, does it take to get to the bottom of the garage from the top?
Answer with step-by-step thinking: First find the total number of gates someone has to pass through: 12 floors / 3 floors / gate = 4 gates. Then find the total time someone spends waiting at the gates: 4 gates * 2 minutes / gate = 8 minutes. Then convert that time to seconds: 8 minutes * 60 seconds / minute = 480 seconds. Then find the time to drive through one floor in seconds: 800 feet / 10 feet / second = 80 seconds. Then multiply the time per floor by the number of floors to find the total driving time: 80 seconds / floor * 12 floors = 960 seconds. Then add the total driving time to the total time waiting at the gates to find the total time to get to the bottom: 960 seconds + 480 seconds = 1440 seconds.
So the answer is 1440.


Question: Johan has a ten-bedroom house with 8 walls in each room. He paints 3/5 of the rooms in the house green and paints the rest of the rooms with purple color. How many walls in the house did he paint purple?
Answer with step-by-step thinking:
Since Cristian's house has ten rooms, he painted 3 / 5 * 10 = 6 rooms with green color. The number of rooms he painted with purple is 10 - 6 = 4 rooms. Since each room in the house has eight walls, the number of walls painted purple is 8 * 4 = 32.
So the answer is 32.
