Final answer:
To find out how much jam Eva jarred if she spent 8 days making jam, set up a direct proportion and solve for x. Eva would have jarred 64 liters of jam if she spent 8 days making jam.
Step-by-step explanation:
To find out how much jam Eva jarred if she spent 8 days making jam, we need to set up a proportion based on the relationship being directly proportional.
Since Eva jarred 8 liters of jam in 4 days, we can set up the proportion:
4 days : 8 liters = 8 days : x liters
To solve the proportion, we can cross-multiply:
4 * x = 8 * 8
x = 64 liters
Therefore, Eva would have jarred 64 liters of jam if she spent 8 days making jam.
