Converting simple future active to passive requires: object (a lot of money) becomes subject + will + be + past participle (paid) + agent (by her). The future passive maintains “will” and adds “be” before the past participle. This structure indicates a future action with focus on the money rather than the payer. Future passive is common in formal contexts like contracts, predictions, and announcements.
