If p varies inversely as Q2 and p = 4 when Q =0.5, find p when Q = 1.5

a) k = 8

b) p = 12

Step-by-step explanation:

Step(i):-

Given that p varies inversely as Q

                           p∝ Q

                           p = k Q

Given that p = 4 and Q = 0.5

                        4 = k (0.5)

                       k =

Step(ii):-

 Given that Q = 1.5

                  p = k Q

                 p = 8 (1.5)

                p = 12

x/3-10=8

x/3=18

x=48

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
