a function grows exponentially at a rate of 10%. If the value at t=2 is 908.56 what is the value of (a) in the formula: f(x)=a.b(x)

Math
equation best describes exponential decay a. y=a.b(x) with o<b<1 b. y=a.b(x) with o<b_<1 c. y-a.b(2) with o<x_<1 d. y=a.b(x) with a>o

ah ok, i see your point. i had worked out that P = $500 - 2xQ(10x20) as MC = MR (100=100), so price was 300 and output 20. the tax would mean a reduction in output to 15 units, by my calcs but how can i work out the corresponding price.

Economics
sorry, i understood that, but as the prices go up the output goes down. but how can you recalculate the price. output drops to 15 in an earlier question, but i cant get my head around working out the price

Economics
got this from my teacher, A monopolist faces a demand curve given by the following equation: P = $500 − 10Q, where Q equals quantity sold per day. Its marginal cost curve is MC = $100 per day. Assume that the firm faces no fixed cost. and have the answers for most, but c...
