Question

A sports tournament has 8 teams. Each team has k players. Using k, write an expression for the total number of players in the tournament.

Answer 1

I would go with 8(k)
Think of it this way: If k were to equal 7, then you would do 8x7. But because you don’t know what k is, your expression would be 8(k). It’s the same thing, you just can’t find an answer for 8(k) whereas you can find the answer for 8x7
Good luck on your homework :)
