The number x of bicycle helmets a retail chain is willing to sell per week at a price of $ps given by x = 79p-9-300, 20 SpS 100, Complete parts (A) and (B) x= 1000-51x+9 70 20 0 20 40 60 80 100 120 Price (Dollars) dx (A) Find- dp dx dp (B) Find the supply and the instantaneous rate of change of supply with respect to price when the price is $91. Interpret your results When the price is S91, the supply is (Type an integer or a decimal.) When the price is S91, the instantaneous rate of change of supply with respect to price is (Type an integer or a decimal.) ate ofbicycle helmets per dollar At a price of $91, the supply isbicycle helmets per week and supply is Type integers or decimals.) decreasing ncreasngExplanation / Answer
A)79/sqrt(9+p)
B)supply=79sqrt(9+91) -300
=79*sqrt100 -300
=790-300
=490
instantaneous rate =79/sqrt(9+91)
=79/10
=7.9
increasing at 7.9
