Answer:
Step-by-step explanation:
Total weight of all of the filled jars with jam = 211.2 ounces
When empty, each jar weighs 1.2 ounces
Total weight of 2 dozens of empty jar = 24 × 1.2 ounces
= 28.8 ounces
Total weight of jam in 2 dozens jar = Total weight of all of the filled jars with jam - Total weight of 2 dozens of empty jar
= 211.2 ounces - 28.8 ounces
= 182.4 ounces
The weight of jam in one jar = 182.4 ounces / 24 jars
= 7.6 ounces
The weight of jam in one jar = 7.6 ounces
