If Molly scored a total of 27 points in the basketball game and she scored n points in the last half of the game, write an expression to determine the number of points she scored in the first half of the game.

Assume that the number of points she scored in the first half is m.

We are given that she scored a total of 27 points and the the points she scored in the second half is n.
This means that:
Total score = score in first half + score in second half
27 = m + n
m = 27 - n

Therefore, your desired expression is:
m = 27-n
