50s + 500u < = 2000

u < = 3

s > = 20

10 soldiers, 2 upgrades ... will not work because u = 20

20 soldiers, 4 upgrades ... will not work because u < = 3

30 soldiers, 3 upgrades

50 (30) + 500 (3) < = 2000

1500 + 1500 < = 2000

3000 < = 2000 (nope ... will not work)

40 soldiers, 0 upgrades

50 (40) + 500 (0) < = 2000

2000 + 0 < = 2000

2000 < = 2000 (correct)

answer is : 40 soldiers and 0 upgrades
