A gecko eats 70 crickets every three days. The first day she eats 30% of the crickets. The second day she eats 6 less than the first, and the third day she finishes up the remaining crickets. How many crickets does she eat on the third day? Give the rationale and then the answer.
Let's think step by step. Day 1:70(.30) = 21 crickets. Day 2:21 - 6 = 15 crickets. Day 3:70 - 21 - 15 = 34 crickets.. The answer is: 34.

Karen’s work tote bag is twice the weight of her husband Kevin’s briefcase when the briefcase is empty. When Kevin puts his laptop and work papers in his briefcase, it is twice the weight of Karen’s tote. Kevin’s work papers are a sixth of the weight of the contents of his full briefcase. If Karen’s tote weighs 8 pounds, how many more pounds does Kevin’s laptop weigh than Karen’s tote? Give the rationale and then the answer.
Let's think step by step. Kevin’s full briefcase is 2 * 8 = 16 pounds. His empty briefcase is 8 / 2 = 4 pounds. The contents of his briefcase weigh 16 - 4 = 12 pounds. His work papers weigh 12 / 6 = 2 pounds. Thus, his laptop weighs 12 - 2 = 10 pounds. Therefore, Kevin’s laptop weighs 10 - 8 = 2 pounds more than Karen’s tote.. The answer is: 2.

Ann's favorite store was having a summer clearance. For $75 she bought 5 pairs of shorts for $7 each and 2 pairs of shoes for $10 each. She also bought 4 tops, all at the same price. How much did each top cost? Give the rationale and then the answer.
Let's think step by step. She bought 5 shorts at $7 each so 5 * 7 = $35. She bought 2 pair of shoes at $10 each so 2 * 10 = $20. The shorts and shoes cost her 35 + 20 = $55. We know she spent 75 total and the shorts and shoes cost $55 which left a difference of 75 - 55 = $20. She bought 4 tops for a total of $20 so 20 / 4 = $5.. The answer is: 5.
