2. the wage bill of the employer decreases
If initial wage bill = 11x* 13y=143xy
New wage bill= 9x*15y= 135xy
So there is decrease in wage bill.

Consider the graph G0 with 3 components which are triangles. G0 has 9 vertices labeled
A to I and 9 edges (A, B), (B, C) … as shown below.
If each vertex of G0 is assigned a red or a green color, then we say that an edge
is colored if its ends have different colors.
Ajai and Rekha color the vertices of G0 in the following manner. Ajai proposes a
color (red or green) and Rekha chooses the vertex to apply this color. After 9 turns,
all the vertices of G0 are colored and the number of colored edges is counted.
Suppose Ajai would like to maximize the number of colored edges while Rekha would
like to minimize the number of colored edges. Assuming optimal play from both
players, how many edges will be colored? Explain your reasoning
