Answer:
It will take 29 days to lay the track
After 18 days the crew still has 77 miles of track left to lay
Step-by-step explanation:
203÷7
=29 days
L= 203 - 7(18)
L= 203 - 126
L= 77
I hope this is right but:
Let n=number of full time employees
260<=20+n*40
260-20<=N*40
240<=n*40
n>=240/40
n>=6 full time employees
which means he would have to hire at least 6 or more fully time employees
Though I'm not sure if the attached file is the graph you are looking for
$52 × .06 = 3.12
52 + 3.12 = 55.12
55.12 × 0.15 = 8.27
55.12 + 8.27 = 63.39
