Answer:

You will need 39 nickels and 13 dimes.

Step-by-step explanation:

First you would find the number by choosing a number for example 10 so 10*5 which is 50 cents because, we are talking money here

So 39*5=195 which converts to $1.95

Next you would write that number down and divide 39 by 3 which would be 13

Then 13*10 would be 130 which would be converted into $1.30

Lastly you would add $.195 and $1.30 which would be $3.25

Therefore your answer is 39 nickels and 13 dimes
