Answer:
1st: 0.04, 0.04, 0.25, 0.4
2nd: 0.06, 0.16, 0.6, 60
3rd: 0.07, 0.7, 0.075, 0.75, 7.5
4th: 0.02, 0.18, 0.2, 200
5th: 0.009, 0.09, 0.9, 0.95
6th, 0.1, 0.12, 1, 10
Step-by-step explanation:
Okay so the equation. Lets say e is explorers and v is flying vs and m = money.
e + v > or = 30.
80e + 5v =m.
e < or = 20\
v < or = 20.
Okay, the most money he could make would be if he made 20 explorers at 80 dollars and 10 vs at 5 dollars.
Total money...
1600 + 50 = 1650.
So he could make $1650.
