Q. 584584\newlineChapter 77 Rational Expressions and Equations\newline2323. Andrew is on a low-carbohydrate diet. If his diet book tells him that an 88 -oz serving of pineapple contains 19.2 g 19.2 \mathrm{~g} of carbohydrate, how many grams of carbohydrate does a 55-oz serving contain?
  1. Calculate Carbs per Ounce: We need to find out how many grams of carbs are in 1oz1\,\text{oz} first, so we divide the carbs in the 88-oz serving by 88. \newline19.2g÷8oz=2.4g19.2\,\text{g} \div 8\,\text{oz} = 2.4\,\text{g} per oz.
  2. Multiply Carbs for 55 Ounces: Now we multiply the carbs per oz by the number of oz in the serving we want, which is 55 oz.\newline2.4g/oz×5oz=12g.2.4\,\text{g}/\text{oz} \times 5\,\text{oz} = 12\,\text{g}.
