Marvin counts six $5 bills. write each value that he counts. what pattern do you see in the one digits of the values he counts?

The pattern is that multiples of 5 either have a 5 or a 0 in the ones place

Step-by-step explanation:

One $5  ->   total is $5     (a five in the ones place)    

Two $5s ->  total is $10    (a 0 in the ones place)

Three $5s  ->   total is $15     (a five in the ones place)    

Four $5s ->  total is $20    (a 0 in the ones place)

Five $5  ->   total is $25     (a five in the ones place)    

Six $5s ->  total is $30    (a 0 in the ones place)
