Part b c and d please help

b) Y =5.73X +4.36

C)  =5.73225*(21)X +4.359

    124.73625

D) 163.728 = 5.73X +4.36  

     X = (163.728 - 4.36)/5.73

     X = 27.81291449

  Year would be 2027

Step-by-step explanation:

x1y1  x2y2

427.288  1696.075

(Y2-Y1)(96.075)-(27.288)=   68.787  ΔY68.787

(X2-X1)(16)-(4)=    12  ΔX12

slope=5 41/56    

B=4 14/39    

Y =5.73X +4.36      

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
