In a chemistry lab, there are 9.52 grams of a powdered substance in a container. Max needs to place an equal amount of the powdered substance into each of 3 glass plates. The amount of powdered substance he places into each glass plate is 1.98 grams. Max estimates that there are about 4.5 grams of the powdered substance remaining in the container. Is his statement reasonable? OA. This is reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 1.5 grams. Since 9 - 3(1.5) = 4.5, there would be about 4.5 grams of the powdered substance remaining in the container. B. This is not reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 1 gram. Since 9 - 3(1) = 6, there would be about 6 grams of the powdered substance remaining in the container. Oc. This is not reasonable because 9.52 grams can be rounded to 9.5 grams and 1.98 grams can be rounded to 2 grams. Since 9.5 - 3(2) = 3.5, there would be about 3.5 grams of the powdered substance remaining in the container. OD. This is reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 2.5 grams. Since 9 - 3(2.5) = 1.5, there would be about 1.5 grams of the powdered substance remaining in the container.
