Question: Julia is performing in her high school musical this weekend and her family wants to come to the show. Tickets are $12 for adults and $10 for children. If her mom, dad, grandma, and three little sisters come to the show, how much will the total be for their tickets?
Answer with step-by-step thinking: The cost will for 3 adults will be $12 / adult x 3 adults = $36. The cost for 3 children will be $10 / child x 3 children = $30. The total cost will be $36 + $30 = $66.
So the answer is 66.

Question: Jacob is trying to eat less than 1800 calories a day. If he eats 400 calories for breakfast, 900 calories for lunch, and 1100 calories for dinner, how many more calories did he eat than he planned?
Answer with step-by-step thinking: First add up the calories from all three meals: 900 + 400 + 1100 = 2400. Then subtract Jacob's goal from the number of calories he actually ate: 2400 - 1800 = 600.
So the answer is 600.

Question: Keaton climbed a 30 feet ladder twenty times while working at the construction site. Reece, also working at the same site, climbed a ladder 4 feet shorter than Keaton's ladder 15 times. What's the total length of the ladders that both workers climbed in inches?
Answer with step-by-step thinking:
If Keaton climbed his ladder twenty times, he covered a length of 30 * 20 = 600 feet. Reece's ladder, 4 feet shorter than Keaton's ladder, was 30 - 4 = 26 feet long. If Reece climbed the ladder 15 times, he covered a length of 15 * 26 = 390 feet. Keaton and Reece's total length covered while climbing the ladders is 390 + 600 = 990 feet. Since one foot is equal to 12 inches, the total length they climbed the ladders in inches is 12 * 990 = 11880 inches.
So the answer is 11880.
