A motor scooter purchased for $1,000 depreciates at an annual rate of 15%. Write an exponential function, and graph the function. Use the graph to predict when the value will fall below $100. I know that the function is V(t)=1000(1-0.15)^t but I cant find the value of t?

I REALLY need help with this problem, I understand how to write the function, but I dont have a graphing calculator and wolfram alpha doesn't give me the correct graph so its very hard to solve this problem
