Alberto feeds his fish the same amount of food each day. A 2 ounce jar of fish food flakes has enough food for Alberto to feed his fish for 100 days. how many ounces of food will alberto need for 110 days?

If the 2-ounce jar of fish food is enough for 100 days, then for 110 days you can say: 2/100 = 0.02 ounces of fish food per day in 100 days. So, because there are 10 more days, 10 x 0.02 = 0.2 So, add 2.0 + 0.2 = 2.2. The answer is 2.2 ounces of food.
