a. Write and Evaluate an expression to find Lily's score.

b. Write and Evaluate an expression to find Rose's score.

c. Who won the game?

Answer 1

a. Lily gains 5 points two times, loses 12 points, and then gains 3 points.

So the expression for finding Lily's score will be ......

b. Rose loses 3 points 2 times, loses 1 point, gains 6 points, and then gains 7 points.

So the expression for finding Rose's score will be ......

c. As Rose's score is greater than Lily's score and the player with the most points at the end wins, so Rose will win the game.

Explanation:

Answer 2

a. Lily gains 5 points two times, loses 12 points, and then gains 3 points.

So the expression for finding Lily's score will be ......

`(5*2)-12+3\\ \\ =10-12+3\\ \\ =13-12=1`

b. Rose loses 3 points 2 times, loses 1 point, gains 6 points, and then gains 7 points.

So the expression for finding Rose's score will be ......

`-(3*2)-1+6+7\\ \\ =-6-1+6+7\\ \\ =-7+13=6`

c. As Rose's score is greater than Lily's score and the player with the most points at the end wins, so Rose will win the game.
