Answer:
1:the answer is 30,
2: is NO it dose NOT taste the same and here's why:
Patricia's ratio = 1:6 meaning for every tble spoon she will add 6 ounces of water her chart would look like
1:6
2:12
3:18
4:24
5:30
Now Kevin ratio would be 1:8
meaning for every tble spoon of lemon juice he put 8 ounces of water
his chart-
1:8
2:16
3:24
4:32
5:40.
so in short terms you can just say
No because Patricia's ratio is 1:6
and Kevin's is 1:8 meaning more water is going into Kevin's unlike Patricia's.
