The weight limit for luggage at the airport is 22 kilograms per person. rico packs two suitcases and finds their weights to be 8,500 grams and 9,200 grams. how many more grams can be packed without going over the weight limit?

Eg. w is the weight addition can be packed
Total weight is less than or equal to 22 kg. The inequality system will be
8,500 gr + 9,200 gr + w ≤ 22 kg

Change the weight into gram unit
8,500 gr + 9,200 gr + w ≤ 22 × 1,000 gr
8,500 gr + 9,200 gr + w ≤ 22,000 gr

Solve the inequality system
8,500 gr + 9,200 gr + w ≤ 22,000 gr
17,700 gr + w ≤ 22,000 gr
17,700 gr - 17,700 gr + w ≤ 22,000 gr - 17,700 gr
w ≤ 4,300

Rico can pack no more than 4,300 grams

Idon’t know this and this isn’t middle school work

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.

the answer is 18.
