 
 <prompt> Gail ta yi matsayin kudin a cikin kantin ta wanda ke dauke da $100. Ta dauka bakwai kudin $5 da bakwai kudin $20, kuma sauran su ne kudin $10. Me kudin $10 ne a cikin kantin ta? <response>: Four $5 bills amount to $5 x 4 = $20.
Three $20 bills amount to $20 x 3 = $60.
So Gail's $5 and $20 bills amount to $20 + $60 = $80.
Thus, her $10 bills amount to $100 - $80 = $20.
Therefore, she has $20/$10 = 2 $10 bills.

The answer will be 2.
