Answer
Amount paid by Company A more than the amount paid by company B = 1400
Work Step by Step
Company A initially pay amount $x_{1}$ = 24000
Company A amount Raise per year (d) = 1600
Amount paid by company A in 10 years $x_{10}$ = $x_{1}$ + (n - 1) d
= 24000 + (10 - 1) 1600 = 24000 + 14400 = 38400
Company B initially pay amount $x_{1}$ = 28000
Company B amount Raise per year (d) = 1000
Amount paid by company B in 10 years $x_{10}$= $x_{1}$ + (n - 1) d
= 28000 + (10 - 1) 1000 = 28000 + 9000 = 37000
Amount paid by Company A more than the amount paid by company B = 38400 - 37000 = 1400
