A small bag of flour weighed 21 ounces. A large bag was 11% heavier. How much does the large bag weigh?

By reading the problem you know that the second bag is going to be 21+11% of 21, since it is 11% heavier. So first find what 11% of 21 is. Convert 11% to decimal. Now you have. 11, now multiply this by 21. So you'll have 21x. 11=2.31. So you know that the second bag is 2.31 heavier than the first. Add this to the original weight. 21+2.31=23.31. So the large bad weighs 23.31 ounces.

Answer:22.31
