Question: Mr. Callen bought 10 paintings at $40 each and 8 wooden toys at $20 each from the crafts store to resell at a profit. However, when he sold the items, the selling price of a painting was 10% less and the selling price of a hat 15% less. Calculate the total loss Mr. Callen made from the sale of the items.
Answer: Step-by-step reasoning process: If he sold a painting at a 10% loss, then he made a 10 / 100 * $40 = $4 loss on each painting. since he bought 10 paintings, the total loss he made from selling the paintings is 10 * $4 = $40. He also made a loss of 15 / 100 * 20 = $3 loss from selling each wooden toy. Since he bought 8 wooden toys, the total loss he made was 3 * 8 = $24. In total, Mr. Callen made a loss of $40 + $24 = $64 from the sales of the items.
So the answer is 64.

Question: Lagoon island is populated by alligators. Half the alligators are male. The rest are female. Among the females, 40% are juveniles. There are 15 adult females. How many male alligators are there?
Answer: Step-by-step reasoning process: 60% of female alligators are adults because 100 - 40 = 60. There are 25 female alligators because 15 / .6 = 25. There are 50 alligators in total because 25 / .5 = 50. There are 25 male alligators because 50 / 2 = 25.
So the answer is 25.

Question: John orders food for a massive restaurant. He orders 1000 pounds of beef for $8 per pound. He also orders twice that much chicken at $3 per pound. How much did everything cost?
Answer: Step-by-step reasoning process: The beef cost $8 * 1000 = $8000. He buys 1000 * 2 = 2000 pounds of chicken. So the chicken cost 2000 * $3 = $6000. So the total cost is $8000 + $6000 = $14,000.
So the answer is 14000.

Question: One-third of a class of 39 students took part in a math competition. How many students did not participate in the competition?
Answer:
Step-by-step reasoning process: Since one - third of the class participated, there are 39 * 1 / 3 = 13 students who participated in the competition. This means that 39 – 13 = 26 students did not participate.
So the answer is 26.
