For a give-away at the mall, the color of the entry forms changes every hour on the hour, and once a color has been used, it is not used again that day. To limit the number of entries, a person may not fill out more than one form of any color. Using the table below, what is the maximum number of total entries Sarah and her three friends could have submitted during the day?
Sarah could fill out the entry forms issued at 8, 9, 10, 11, 12, 1, 2, 3, 4 = 9 forms
Davie could fill out the forms issued at 9, 10, 11, 12, 1, 2 , 3 = 7 forms
Zeb could fill out the forms issued at 10, 11, 12, 1, 2, 3 , 4 = 7 forms
Alishe could fill out the forms issued at 12 , 1, 2, 3 , 4 = 5 forms
So the max entries are 9 + 7 + 7+ 5 = 28
