A salvage yard sells 2 tons of iron and 1 ton of
aluminum to a recycling plant. How many
pounds of iron and aluminum does the salvage
yard sell?
A 3 lb
B 300 lb
C
D

To solve this, you first need to convert tons to pounds. There are 2,000 pounds in a ton. So, for the iron, you have 2 tons which equals 4,000 pounds, and for the aluminum, 1 ton equals 2,000 pounds. Adding these together gives you 4,000 lb + 2,000 lb = 6,000 lb.

The correct answer is D .

To ensure you don’t mix up units in the future, a good habit is to write down conversion factors when first approaching a problem. This helps solidify what each unit represents. Keep a little cheat sheet handy for quick conversions!

Also, be conscious of common mistakes like misreading the problem or overlooking the unit conversions. Always double-check your calculations, especially when dealing with multiple units. A careful review can save you from those pesky little errors!
