The weight is proportional to the price. So if 10lb cost $18.24, quarter as much (2.5lb) would cost four times less($18.24÷4=$4.56).
It would be both the penny and the quarter.
The hundredth place would be the third one from the left.

So therefore the quarter and penny both have a five in that spot.
