Question

Prompt

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?

1.47 a + 1.39 b = 35 (1.43)

1.39 a + 1.47 b = 35 (1.43)

1.43 a + 0.39 b = 35 (1.47)

1.39 a + 1.43 b = 35 (1.47)
