No. of bags for $1 = 30/8.4 bagsWeight for $1 = 175/1.96 g
Weight for 1 bag = (175/1.96 g) / (30/8.4) = (175/1.96) × (8.4/30) g = 25 g

A gram costs 1.96/175 = 0.0112
Your 30 bags cost $0.28 each
So each one weighs
0.28/0.112 = 25 grams
Your 30 bags cost $0.28 each
So each one weighs
0.28/0.112 = 25 grams

30 bags of popcorn cost $8.40. 175g of popcorn cost $1.96 when bought in these bags. How many does one bag of popcorn weigh?
In $1.96 popcorn purchased =175 g
In $ 1 popcorn purchased =175/1.96 gm
In $ 8.40 popcorn purchased =(175/1.96)×8.40 =175×8.40/1.96=750 gm
Hence 30 bags weigh = 750 gm
Weight of 1 bag =750/30 = 25 gm
In $1.96 popcorn purchased =175 g
In $ 1 popcorn purchased =175/1.96 gm
In $ 8.40 popcorn purchased =(175/1.96)×8.40 =175×8.40/1.96=750 gm
Hence 30 bags weigh = 750 gm
Weight of 1 bag =750/30 = 25 gm
