The volume of a certain hot air balloon is increased by 10% and flown for several hours. Then the new volume is decreased by 10%. What is the percentage volume of the hot air balloon at the end as compared to its very first volume?

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
