Qs = 2 P - 100 P = price of a powerbank
Qs = number of supplied powerbanks X 1,000
1) How many powerbanks are supplied at a price of € 80?
P = 80 --> Qs = 2 X 80 - 100 = 60 --> 60,000
2) How many powerbanks are supplied at a price of € 100?
P = 100 --> Qs = 2 X 100 - 100 = 100 --> 100,000
3) What is the minimumprice? (hint: Qs = 0)
Q = 0 --> 2 P - 100 = 0
P = 50
