A bank teller has t dollars, all in $5 bills. What expression represents the number of $5 dollar bills the teller has?

5t

5t is how many dollars in t $5 bills

we want t/5, the number of $5 bills to make t dollars.

Let's assume that the number of $5 bills the teller has is represented by the variable 'b'. To find the expression that represents the number of $5 bills, we can divide the total amount of money the teller has, represented by 't', by the value of each bill, which is $5.

Therefore, the expression that represents the number of $5 bills is:

b = t/5

To determine the number of $5 bills the bank teller has, we can divide the total amount of money the teller has (t dollars) by the denomination of each bill, which is $5.

So, the expression that represents the number of $5 bills is:

t / 5
