Answer:
Yes, both shampoo and water will be enough
Given that:
Number of long and short hair member who can wash their hair ; with amount of water less than 5600 litres
To check if bathroom has enough water and shampoo for 8 long haired and 7 short haired members.
L = long-haired ; S = short-haired
70L+ 60S < 5600
Check the constraint for amount of water :
70L+ 60S < 5600
L = 8 ; S = 7
70(8) + 60(7) < 5600
560 + 420 < 5600
980 < 5600
Constraint satisfied
Number of long and short hair member who can wash their hair with shampoo not more than 2.5 litres
0.02L + 0.01S ≤ 2.5
L = 8 ; S = 7
0.02(8) + 0.01(7) ≤ 2.5
0.16 + 0.07 ≤ 2.5
0.23 ≤ 2.5 (constraint satisfied).
