A group of friends decide to meet for pizza, and one friend calls ahead to order the pies. However, three people in the group do not show up at the pizza parlor. The friends who do show up figure that they each add $3 to their original share, to cover the bill, which totals $70. How many friends eat pizza?
Hint 1: Let’s look at what were given:
Hint 2:

Hint 3:
