I don't think you can make this profitable but it's certainly cheaper than doing it without discounts:
 * Formula E: Showcase - requires 553 and BRL2,726,200 to win 72 however these costs are irrelevant as cars require more upgrading for Formula E.
 * Formula E: Experience - requires all cars to be upgraded with 648 and BRL3,318,300 to win 75 and 300 bonus

So assuming a 50% discount costs are:
 * 3 x ( 648 / 2 ) = 972
 * 3 x ( 3,318,300 / 2 ) = BRL4,977,450

Rewards are:
 * 72 + 75 + 300 = 447

Net cost:
 * 972 - 447 = 525 and BRL4,977,450
