ANSWER:
6500 pounds
STEP-BY-STEP EXPLANATION:
To know the answer, we must first know the equivalence between tons and pounds, since it is the only way they can be added.
We know that 1 ton equals 2000 pounds, therefore:
[tex]\begin{gathered} 2\text{ tons}\cdot\frac{2000\text{ pounds}}{1\text{ ton}}=4000\text{ pounds} \\ \text{then, } \\ 2500\text{ pounds + 4000 pounds }=\text{ 6500 pounds} \end{gathered}[/tex]
