Answer:
40 quarts
Step-by-step explanation:
For this question, you set up a proportion. You know that Kelsey jarred 12 quarts of jam after 3 days so you set 12 quarts/3days equal to x quarts/10days.
12 quarts/3 days=x quarts/10 days
Then, you can cross multiply. You get 3x=120.
Then, divide 3 by both sides to get x by itself.
120/3=40
Your answer is 40 quarts.
Hope that helps!
