Answer:
a) 10 pieces of 2/3 pound can be made.
b) 0.54 pounds of wax is left over.
Step-by-step explanation:
Total amount of clear wax available = pounds
So, the maker has in total 4.5 pounds of wax
Now, The weight of each piece = pounds
To find the number of pieces that can be made out of 4.5 pounds of wax,
let that number = n
So,
or, n =
So, nearly 6 pieces can be made completely out of the clear wax
Left over amount of wax = Total weight - Weights of the pieces made
= 4.5- 6(0.66)
= 0.54 pounds
Hence, 0.54 pounds of wax is left over
