From the statement, we know that the grain trader buts the following amounts:
• 3200 pounds,
,
• 7200 pounds,
,
• 600 pounds.
To find the total weight of the purchase, we simply add the three quantities:
[tex]T=3200\text{pounds}+7200\text{pounds}+600\text{pounds}=11000\text{pounds.}[/tex]
Now, taking into account that:
[tex]1\text{ton}=1000\text{pounds.}[/tex]
We can write the total weight as:
[tex]T=11000\text{pounds}=11\cdot(1000\text{pounds)}=11\cdot(1\text{ton)}=11\text{tons.}[/tex]
Answer
The total weight of the purchase is 11 tons.
