Answer:
a = 51
b = 51 (??not so sure)
c = 20 cents

Answer: This is what Khan Academy said the answer was
If Marcy would want to have 2 bags with the equal amount of sauce from a 9.98 pound bag of sauce, then all she needs to do is to divide the total amount of sauce, which is 9.98, by 2 bags. So if she would do this, then the equation will be 9.98/2. The answer to this problem would be 4.99 pounds of sauce per bag. This makes since because 4.99 pounds (in the first bag) + 4.99 pounds (in the second bag) will make up 9.98 pounds which is the total amount of sauce Marcy has.
