Question

A player gets a "cap" each time they play for their national team.

The players in Team A have a total of 36 caps. The players in Team B have a total of 12 caps. Mel moves from Team A to Team B.
Now, the players in Team A have twice as many caps in total as the players in Team B.
Work out how many caps Mel has. ​

Answer 1

Hello!

x = number of caps of Mel

36 - x = 2(12 + x)

36 - x = 24 + 2x

36 - 24 = 2x + x

12 = 3x

x = 12/3

x = 4

The answer is 4.

verification:

36 - 4 = 32

12 + 4 = 16

16 x 2 = 32 or 32/2 = 16

it's correct.
