If there are d $1 bills their value is $1 × d, or d dollars.
Each $5 bills is worth 5 times as much so if there are f bills their value is $5 × f, or 5f dollars.
Thus the expression for the total would be d + 5f dollars.
It is called "to evaluate" the expression.
Is the value obtained when all the variables have been given their value and the expression has been calculated according to mathematical rules.

Reading the question very carefully, I'd have to say "none". If the stack consists of "900 dollar bills",then there are no "50 dollar bills" in it.But the questioner is probably referring to equivalent values.900 dollar bills have a face value of $900.00 . In order to match that same face value with $50.00 bills,you need 18 of them.
