Answer:
I came up with -12
Step-by-step explanation:
8 workers = 6 days to complete
x workers = 4 days faster to complete
6/4=1.5 days faster
1.5 x 8 = 12 workers needed to complete the wall in fours days
B would be your answer
5 > -2
-3+5 < 4
10^-8 = 1/(10^8)
10^8 = 100000000
1/100000000 is your answer
hope this helps
