Question

At Saturday night's football game there were 18 less fans than half the fans at Friday night's game. There were "x" fans at Fridays game. Write an expression to represent the number of fans at Saturdays game.

Answer 1

`\boxed{ ( 1)/( 2)x - 18}`

Explanation:

x = fans at Friday's game

½x = half the fans at Friday's game

½x – 18 = 18 fewer than half the fans at Friday's game

`\boxed{ ( 1)/( 2)x - 18}` = fans at Saturday's game.
