How many marks is this worth? It's not easy to see that bit, and it helps you to determine how much work is required (At least in Scotland it does)

What you're looking for is a value of t which makes X = 2000 i.e.

2000 = 275 x 10^(0.018t)

I'm sorry, I used to be able to do this but I've totally forgotten, let me have a think and I'll get back to you.

i was in the top group in maths (well one of the top ones, except i didnt have to do statistics) and i found it easy, maybe thats just me lol. i dunno what happened.
i just did an as level in ict and my friend did an as in electronics. both are ok but i found that our retarded teachers made the lessons pretty pointless.
anyway i still cant figure it out
