Solution:

The increase in 2011 to 2012
Hatchback =

{800- 650}/650 ×100=23.07%

Sedan

= { 625 - 575}/575 ×100=8.69%

SUV

= {750-400}/400 ×100= 87.5%

The increase in 2012 to 2013
Hatchback

= 800 ×(100 + 23.07)/100

= 984.56≈ 985

Sedan

=625× (100 + 8.69)/100

= 679.312 ≈ 679

SUV

= 7 5 ×(100+8- 7.5)/100

= 1406.25 ≈ 1406

The total approximate sales in 2013 = 985 + 679 + 1406 = 3069
