Hi,
I'm trying to figure out how to calculate something in Excel. It's basically an acceleration question.
I have 3 numbers.
1) Current Speed.
2) Current Acceleration
3) Acceleration Growth.
Current Speed = 1.
Current Acceleration = 1, so each turn, the speed will increase by the current acceleration.
Acceleration Growth =0.1 Each turn, the Current Acceleration will increase by this much.
I would like to be able to calculate how many 'turns' it will take for the current speed to hit X (for example, 100). Is this possible?
Many Thanks

I was solving this question and my answer is Program B as the cost of the program is $14,570
I want to make sure if the answer is correct.
This was my reasoning:
(28x12.5)x4=1,400+170+13,000=$14,570
