Let x be the number of adults originally going to attend the wedding.
The number of children originally going to attend the wedding is 95 - x.
The cost of the adults attending is 22x.
The cost of the children attending is 195 dollars.
The total cost of food for the original attendees is 22x + 195.
So, 22x + 195 = 1955.
Therefore, 22x = 1955 - 195 = 1760.
So, x = 1760 / 22 = 80.
The number of children originally going to attend the wedding is 95 - 80 = 15.
If Hal and Sal add 2 more adults and 2 more children, the total number of adults will be 80 + 2 = 82.
The total number of children will be 15 + 2 = 17.
The cost of the additional adults is 2 * 22 = 44 dollars.
The cost of the additional children is 2 * 13 = 26 dollars.
The new total cost will be 22 * 82 + 13 * 17 + 44 + 26 = 1804.
Therefore, Hal and Sal will have to pay 1804 - 1955 = 151 dollars more if they add 2 adults and 2 children to their wedding bill.
