The average of 5, 7, 12, and 12, is (5 + 7 + 12 + 12)/4.
(5 + 7 + 12 + 12)/4 = 36/4 = 9.
The average is 9.

To find the average, or mean, you add up all the numbers and divide the sum by the total number of numbers you added up.

5, 7, 12, 12
Add these numbers up ⇒ 5 + 7 + 12 + 12 = 36.
Divide 36 by the number of numbers added up, 4. ⇒ 36 ÷ 4 = 9

The mean of the numbers is 9.

A 35 pound dog eats an average of 2 1/2 cups of dry dog food a day. If you assume that there is a relationship between size and
zimovet [89]
70 / 35 = 2
So the 70 pound dog weights double the weight of the 35 pound dog, so he will eat twice as much.

2 x 2.5 = 5 cups

Meaning he will eat 5 cups of dry dog food a day.

By the same logic a 140 pound dog would have to eat twice what a 70 pound dog eats, that is 10 cups of dry dog food a day, so 7 1/2 cups are not enough.

Challenge: per pound a dog eats more than a cat. Since you know a 140 pound dog eats 10 cups, you can dive 140 by 10, to find out that each cup feeds 14 pounds, so half a cup would be the amount of food to feed a 7 pound dog, meaning that a dog weighing 1 pound less than a 8 pound cat would need the same amount of food, so it eats more than a cat.
