Answer
Amount paid by Company A is more than the amount paid by company B = 600
Work Step by Step
Company A initially pay amount $x_{1}$ = 23000
Company A amount Raise per year (d) = 1200
Amount paid by company A in 10 years $x_{10}$ = $x_{1}$ + (n - 1) d
= 23000 + (10 - 1) 1200 = 23000 + 10800 = 33800
Company B initially pay amount $x_{1}$ = 26000
Company B amount Raise per year (d) = 800
Amount paid by company B in 10 years $x_{10}$= $x_{1}$ + (n - 1) d
= 26000 + (10 - 1) 800 = 26000 + 7200 = 33200
Amount paid by Company A is more than the amount paid by company B = 33800 - 33200 = 600
