Answer:
a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as: 
 
Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71 
 
b) The cost of a ticket for the next game given they have 31 losses is: 
 
Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93
