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!
Solution:
The total number of ways to form a 3 person subcommittee is 13C3 = 286
The total number of ways to choose 1 republican from 5 is 5C1 = 5.
The total number of ways to choose 1 democrat from 6 is 6C1 = 6.
The total number of ways to choose 1 independent from 2 is 2C1 = 2.
By the counting principle, there are 5 x 6 x 2 = 60 ways to select 1 republican, 1 democrat and 1 independent
Therefore the probability that the subcommittee consists of 1 Republican, 1 Democrat, and 1 Independent is:

The answer will be $2.20. Because they only traveled one mile, which is 20 cents. Also the original cost before they even started driving was $2.00.
