Answer:
4 pounds with a membership
29 pounds without
i just added both because i didnt know if you meant 58 extra dollars after bbuying membership or not
Explanation:
58 -50(membership fee)=8
16 divide by 8=2
16$=8 pounds
8$=4 pounds
---------------------------------------
without membership you could buy 29 pounds of apples
58 divide by 16=3.625
3.625 x 8=29
