B. 80 oz
To find the total amount of jam in all 4 jars, we can add up the amount of jam in each individual jar.
1 jar is completely filled with 38.75 oz
1 jar is 2/3 filled with jam, which would be 2/3 * 38.75 = 25.83 oz
1 jar is 1/2 filled with jam, which would be 1/2 * 38.75 = 19.38 oz
1 jar is 3/4 filled with jam, which would be 3/4 * 38.75 = 29.06 oz
Adding all these amounts together:
38.75 + 25.83 + 19.38 + 29.06 = 113.02 oz
Since we are looking for the most reasonable estimate, we can round this to the nearest 10 to get 110 oz, which is closest to 80 oz.
