Answer:
145.8 pounds
Step-by-step explanation:
So, if there is 9720 pounds total, and 98.5% of it must be pure paper, than 1 - .985 is how much can be impurities.
1-.985 = .015 or 1.5%
Now lets multiply .015 times 9720
.015(9720) = 145.8
The maximum weight of impurities is 145.8 pounds
It is 7/1 because you divide by 7 for 49/7 and 7/7 divde by both and you''ll get 7/1
