Mr. Ward and Mrs. Ward typically vote oppositely in elections, so their votes "cancel each other out." They each gain 30 units of utility from a vote for their positions (and lose 30 units of utility from a vote against their positions). However, the bother of actually voting costs each 15 units of utility. The following matrix summarizes the strategies for both Mr. Ward and Mrs. Ward.

Using the given information, fill in the payoffs for each cell in the matrix. For example, in the top left cell, fill in the payoffs for Mr. Ward and Mrs. Ward if they both vote. (Hint: Be sure to enter a minus sign if the payoff is negative.)
