Tickets to a baseball game cost $3 for a child’s ticket and $5 for an adult ticket. at the last game, $521 was collected when 139 people attended the game. which value could replace x in the table so that a single-variable equation can be written and solved to determine the number of child’s tickets, c, sold? 139 521 139 – c 521 – c

139 – c
