Final answer:
Bette has more trail mix and she has ½ pound more than Johnna.
Step-by-step explanation:
To find out who has more trail mix, we need to compare the amounts of trail mix Bette and Johnna have. Bette has 1 pound of trail mix and Johnna has ½ pound of trail mix. We can see that 1 pound is greater than ½ pound, so Bette has more trail mix.
To find out how much more trail mix Bette has, we can subtract the amount Johnna has from the amount Bette has.
1 pound - ½ pound = ½ pound
Therefore, Bette has ½ pound more trail mix than Johnna.
