“Konfyans se yon misté. Yo pa achte sa, ou pa kapab di ban m pou tan.” I don’t understand the use of “tan” in this sentence. Can you explain? Mési.

Tan – this much, so much, an undetermined number

Some examples how it is used.

1.

You may think that the car costs this much, but in reality it costs more than that. - Ou kapab panse machin nan koute tan, men anreyalite li koute plis pase sa.

2.

Here’s a math problem. If the bike costs such amount of money, and the store gives you a rebate of 50%, how much will you pay? – Men yon pwoblèm matematik.  Si yon bekán koute tan, enpi magazen an ba w 50 pousan rabè, konbyen w’ap peye?.

3.

If the company agrees to give free tickets to such number of people, how would we pay for the ones remaining? Si konpani an dakò pou bay tan moun tikè gratis, kouman n’ap fè peye pou rès yo?

By the way your accent is backwards on the “e” in “mistè” and “mèsi”.  It should be “è” instead of “é”.
