Question 191853
Let  D=day  rate

Let  M= Mileage  rate

1)  2D +125M=95.75

2)  4D+350M=226.50

mult (1)  by  2

4D +250M= 191.50

subtract  from  (2)

100M=  35.00

divide  by  100  both  sides  of  eqn

M=  .35

subst  in  (1)

2D +(.35)125 = 95.75

2D + 43.75 = 95.75

subtract  43.75  both  sides

2D=  52

divide  by  2  both  sides

D=  26


check

2(26) + .35 ( 125)  =  95.75   ok

4(26)  +  .35 ( 350) = 226.5    ok
