Reasoning and answer: It will be 90 degrees for 80% of the 15 weeks, for a total of 0.8 * 15 = 12 weeks. It will be 100 degrees F for the remainder of the 15 weeks, or 15 - 12 = 3 weeks. During the 12 weeks when it averages 90 degrees F, he will eat 4 crickets per week for a total of 12 * 4 = 48 crickets. When it averages 100 degrees F, he eats twice as many crickets per week as when it averages 90 degrees F per week, for a total of 2 * 4 = 8 crickets per week. During these 3 weeks, he will eat 8 * 3 = 24 crickets. Therefore, over the 15 weeks, he will eat a total of 48 + 24 = 72 crickets.
The answer: 72

Reasoning and answer: The amount of discount in the first store 950 x 6 / 100 = $57. So, the device costs 950 - 57 = $893 in the first store. The amount of discount in the second store is 920 x 5 / 100 = $46. So, the device costs 920 - 46 = $874 in the second store. The difference in price is 893 - 874 = $19.
The answer: 19
