can you please help me solve this math problem the answer choice are:A. 250, B.1,000, C.2,500, D.10,000

Seyed is correct. There is also another way to to this. Simply multiply the two numbers inside the parenthesis together.

(1/2)(10t)=5t

Now your equation reads 5t=50,000.

Now, solving algebraically, divide both sides by 5. 5t/5=50,000/5

Presto, your answer is exactly the same as what Seyed explained.
