Answer:
Option: B is the correct answer.
B. 2 pounds.
Step-by-step explanation:
It is given that:
Juan’s bag of apples that he bought weighed 31/7 pounds.
Ari’s bag of oranges that she bought weighed 19/3 pounds.
Let Ari's bag be x times heavier than Juan's bag.
This means that:
[tex]x=\dfrac{19}{3}-\dfrac{31}{7}\\\\i.e.\\\\x=\dfrac{19\times 7-31\times 3}{21}\\\\i.e.\\\\x=\dfrac{133-93}{21}\\\\i.e.\\\\x=\dfrac{40}{21}\\\\i.e.\\\\x=1.904[/tex]
which is approximately equal to 2 pounds.
The amount by which Ari's bag is heavier then the Juan's Bag is approx : 2 pounds
