Answer:
42,000 pounds
Step-by-step explanation:
This is a conversion problem.
There are 2000 pounds in 1 ton. We have 21 tons, so we can set up a proportion:
[tex]\frac{2000}{1} =\frac{x}{21}[/tex] , where x is how many pounds are in 21 tons
Cross-multiplying, we get:
x = 2000 * 21 = 42,000
Thus, the answer is 42,000 pounds.
Hope this helps!
