Answer:
Let's denote the current model's battery life by B0, which is 650.0 minutes. We know that each new model's battery life will be 5% longer than the previous model's battery life. So, the battery life of the n-th model (counting from the current model as n=0) can be calculated as:
Bn = B0 * (1.05)^n
After 8 months, the company will release the 8th model (n=8), so we can plug in n=8 into the equation above to find its battery life:
B8 = B0 * (1.05)^8
B8 = 650.0 * (1.05)^8
B8 ≈ 918.0 minutes
Therefore, the latest model's battery life 8 months from now will be approximately 918.0 minutes.
