Answer:
Lisa = 7 hours and 15 minutes
Naila = 10 hours and 45 minutes
Step-by-step explanation:
Naila = N
Lisa = L
Naila worked:
N = 3.5 + L
In total, they worked:
N + L = 18
Lisa worked:
L = h
Substitute values into the total equation
3.5 + L + L = 18
Solve
2L = 14.5
L = 7.25 = 7 hours and 15 minutes
N = 7.25 + 3.5 = 10.75 = 10 hours and 45 minutes
Hope this helps :)
Answer:
see below
Step-by-step explanation:
