Divide both sides by 50 to get t=36. I don't see that as an answer choice? I'm confused. Just wait a sec.
OpenStudy (anonymous):
@CGGURUMANJUNATH, can you help me. I thought that I did it right.
OpenStudy (cggurumanjunath):

OpenStudy (anonymous):
@keke_luvs_u, I don't see t=36 as an answer choice.
