The answer would be 24 8-ounce cups.
First you would find how many quarts over all she has which is 6, then multiply that by 32(which is the amount of ounces are in a quart), then you would get 192 which you divide by 8 to find the total amount of cups you would have which is 24.
Hello!!
25 - 20 = 5
5/20 = 0.25
0.25 * 100 = 25%
Good luck :)
