9 days
Step-by-step explanation:
100 + 50= 150
100 scouts= 12 days
×2 ÷2
200 scouts= 6 days
Midpoint of 100 scouts and 200 scouts= 150
Midpoint of 12 days and 6 days= 9 days
[tex] W + D = 1000 \\
W = 3*D [tex]
Plug the second equation into the first;
[tex] W+D=1000 \\
(3*D)+D=1000\\
4D=1000 [tex]
D = $250
