Question

Rocky made $12\text{kg}$ of trail mix for his family's hiking trip. His family ate $8600\text{g}$ of the trail mix on the hiking trip. How many grams of trail mix did Rocky have left?

• A. $8588\text{g}$
• B. $7400\text{g}$
• C. $2400\text{g}$
• D. $3400\text{g}$

Answer 1

The correct option is D $3400\text{g}$

Rocky made a total trail mix of $12\text{kg}=12000\text{g}$
$\because 1\text{kg}=1000\text{g}$
Given that his family ate $8600\text{g}$.
Rocky is left with $12000\text{g}-8600\text{g}=3400\text{g}$
