After one half of the battery's useful life.
Explanation:
Batteries of the emergency locator transmitter (ELT) must be replaced or recharged after one half of the battery's useful life because if it is exposed to the high temperature for a long period of time such as the air plane parked in the sun will result in the deterioration of battery which may makes the transmitter out of order before the expiry date of the battery.

Answer:
30%
Explanation:
Total profit=$25000
Initial investment=$10000
Return on investment is given by
