(URGENT!!!) Can someone help me with this? For part a), would the equation A=200(15)^m=395 work? In part b), can't I just factor
the number of months into the equation I wrote in part a)? In part c) the rate of change is 4 months, right? And in part d) I would use the same 4 month rate of change to find the answer to that, wouldn't I? If someone can check my answers/correct me where I'm wrong, I'd really appreciate it! :)
A.) 200+15m=395. This is because the initial price is 200, and after that she will add $15/month. The equation you chose would be exponential, meaning the rate would increase as time passed, which is not the case. Instead, the rate is constant, and the only think that changes is m, the number of months.
b.) I believe it will be easier to answer with ^this equation.
c.) The rate of change would be 15, since the rate is increasing monthly by $15.
d.) Once you solve 209+15m=495, you'll have the answer.
