The correct option is
A Bag A
To fit in the garbage can, the bag has to weigh "less" than 5.05 lb.
So, compare the weight of each garbage bag with 5.05 lb.
In case of garbage Bag B,
In the tenths place,
1>0
So,
5.10>5.05
∴ Garbage Bag B is heavier than the maximum capacity of the garbage can.
Next, garbage Bag C having weight 5.50 lb.
At the tenths place,
5>0.
So,
5.50>5.05
∴ Garbage Bag C is also heavier than the maximum capacity of the garbage can.
Finally, compare garbage Bag A having weight 5.01 lb.
In the hundredths place, you get
1<5.
So,
5.01<5.05
∴ Bag A is lighter than the garbage can.
Hence, Bag A can fit inside the garbage can given.
