400,000400{,}000
430,000430{,}000
700,000700{,}000
Answer: C
Concepts:inequalityoptimizationextremal argument
Small hint:
To maximize one salary, pay everyone else as little as allowed
Big hint:
The other 2020 players each earn $15,000\$15{,}000
Solution:
One player’s salary is largest when the other 2020 players each earn the minimum $15,000.\$15{,}000.
That leaves $700,000−20⋅$15,000\$700{,}000-20\cdot\$15{,}000 =$700,000−$300,000=\$700{,}000-\$300{,}000 =$400,000=\$400{,}000 for the single player.
Thus, the correct answer is C.
