Answer:

4 Nickles

Explanation:

to find this out we can devide the total cost (20 ¢) by the worth of the coin we are using (1 Nickel = 5 ¢) as shown below

20 ÷ 5 = 4

what this equation shows is that 4 nickels are needed to add up to a total of 20 ¢

hope this helps

side note, i dont usually say this but at the moment i am 2 crowns away from my next level, so if the answer seems fit to you a crown would be, depending on the other answer, thank you

EDIT:
Additional Example

this method can be applied to most situations, even if you need multiple coin types

say Ron wants to buy a 57 ¢ apple pie slice in exact change, lets assume he has a surplus in the four common coins in his wallet book or pocket

first he uses a quarter and divides as follows

57 ÷ 25 = 2 with a remainder of 7

then he can take a coin of less value then the remainder (in this case a nickel since 5 < 7, and not a dime since 10 > 7)

7 ÷ 5 = 1 with a remainder of 2

and finally with the pennies

2 ÷ 1 = 2

with this info we know that Ron will need 2 quarters, 1 nickel and 2 pennies to have exact change in the least amount of coins
