Final answer:
To determine how much Andre's foreign service premium will increase his base pay, one needs to know the base rate of pay and the percentage increase of the foreign service premium. Typically, military incentives augment the base pay, but without specific rates, an accurate calculation cannot be provided.
Step-by-step explanation:
The question does not provide a specific percentage or rate at which Andre's base pay will be increased due to the foreign service premium. To calculate the exact increase in pay, one would need to know the base rate of pay and the corresponding percentage increase of the foreign service premium. However, typical military pay structures offer incentives such as foreign service premiums, hazardous duty pay, or re-enlistment bonuses that augment the base pay for service members under specific conditions. An estimate can be made if the foreign service premium percentage were provided, using the following formula: Pay increase = Base pay × Foreign service premium rate. Without the actual rate of increase, one can only refer to the Navy's pay scale structures and incentives mentioned in the provided information to get an idea of potential pay increases for serving overseas, learning a trade, and long-term benefits such as retirement pay and disability pensions.
