Step-by-step explanation If Jake has 3 dogs and Bob has five times that amount it would be a simple 3 x 5 equation. because five 3's would be 3+3+3+3+3 = 15
Since the total amount of water that was decreased is equal to 12.8, we would divide it by 4 to see how much it decreased in 1 week assuming it was constant. So, 12.8 divided by 4 is 3.2.
