The answer depends on where his wife and children lived and whether or not the taxpayer chooses to file a joint return. If his wife and children lived for more than six months at the home in the United States and she qualifies for EITC, he would qualify for EITC if he filed a joint return with his spouse. If his wife and children lived with him for more than six months outside the U.S., he would not qualify.
On average there are: 6 slices per small (8-10) pizza, 8 slices per 12 inch pizza (medium), 10 slices on a large (14-16) pizza and 12 slices on an extra-large pizza. You should confirm the number of slices before ordering because this will vary between pizza providers.
How many pizza's that it will take to feed 60 people will vary depending on how hungry people are and the size of the pizza. If you use a large pizza with 10 slices and figure everyone will eat at least 2 slices, you will need about 12 to 20 pizza's.
