1. Historically,40% of the adopted dogs rescued spend an average of 8 days in a kennel costing $10 a day.

Puppies-100
Dogs-650

To calculate the total cost for the adopted dogs rescued, you need to find 40% of the total number of adopted dogs and then multiply it by the average number of days they spend in a kennel and the cost per day.

Step 1: Calculate 40% of the total adopted dogs rescued.
Total adopted dogs rescued = Puppies + Dogs = 100 + 650 = 750
40% of 750 = (40/100) * 750 = 0.40 * 750 = 300

Step 2: Multiply the number of adopted dogs rescued by the average number of days in a kennel.
300 * 8 = 2400

Step 3: Multiply the result from step 2 by the cost per day.
2400 * $10 = $24000

Therefore, the total cost for the adopted dogs rescued is $24,000.
