Answer:
3520 pounds
Step-by-step explanation:
First, we have to find how many pennies equal 2.2 lbs
By seeing that 1 penny equals 4 grams, we can divide 4 into 1,000
By doing this we can find out how many pennies equals 2.2 lbs
It is 250 pennies per 2.2 lbs
Now, it wants 400,000 pennies
So we can do 400,000/250
Which is 1600
1600*2.2 is 3520
So the answer is 3520 pounds
