Answer:
63 coins
Step-by-step explanation:
I am going to assume you are asking how many dollar coins are in the bag, I apologize if I am wrong.
So first, set up the problem. The total number is 517.6 and each coin weighs 8.1
So you would divide 517.6 by 8.1 to get 63.9012346 (which has too many decimal points so round)
But rounding up would get the wrong number because it would be too light for the amount of coins said to be in there, but rounding down gives you 63.
So 63 times 8.1 is 510.3 and the total could consider the weight of the bag into the total 517.6.
