In 2010, a skating team had a total of 35 skaters, each classified as either advanced or intermediate. From 2010 to 2020, the number of advanced skaters on the team increased by approximately 39%, and the number of intermediate skaters on the team increased by approximately 47%. The total number of skaters on the team increased by approximately 43%. Which equation best represents this situation, where $a$ represents the number of advanced skaters on the team in 2010 and $b$ represents the number of intermediate skaters on the team in 2010?

A

$1.47a+1.39b=35(1.43)$

B

$1.39a+1.47b=35(1.43)$

C

$1.43a+0.39b=35(1.47)$

D

$1.39a+1.43b=35(1.47)$
