Answer:
a) 78 oz
b) 84 oz
Step-by-step explanation:
first, you divide 546 by seven because adam is sharing it between him and 6 others. this equals 78 so they each get 78oz of grapefruit.
for the next part of the question, you multiply 12 by 7 to get 84. thats how many oz if grapefruit is not eaten.
