Victor and his three friends (4 people all together) are planning to split a pizza. They want to spend at most $5 per person. Find the maximum (at most) cost of the pizza they can order.
$20, because when one person is supposed to pay at max. $5, and there are 4 people, 5*4= 20. The maximum cost of their pizza should be $20, so each person pays $5.
