If a store receives 665 candies, and each day they sell 5 candies and restock with 10 more candies, how many days will it take until they have 2000 candies in total?

To calculate the number of days, we can subtract the initial quantity of candies (665) from the target quantity (2000). This gives us 2000 - 665 = 1335 candies left to add. Each day, the store adds 10 candies, so we divide the remaining candies (1335) by the number of candies added per day (10). This results in 1335 / 10 = 133.5 days. Since we can't have half a day, we round up to the nearest whole number, which means it will take the store 134 days to have a total of 2000 candies.

Math Question: What is the sum of all odd numbers from 1 to 665?

To find the sum of odd numbers, we use a formula: sum = (n/2) * (first odd number + last odd number), where n represents the number of terms. In this case, the first odd number is 1, the last odd number is 665. So, the number of terms is (665-1)/2 + 1 = 333. Thus, the sum of all odd numbers from 1 to 665 is (333/2) * (1 + 665) = 111,111.

What is the square root of 665?

The square root of 665 is approximately 25.81, rounded to two decimal places.
