Paul owes paula 35 cents and has a pocket full of 5 cent coins 10 cent coins and 25 cent coins that he can use to pay her what is the difference between largest and smallest number of coins that he can use to pay her?

Find the largest number of coins

use the smalles value

5 is smallest

7 of the 5 coins

largest is 7 coins

so find the smallest number of coins

use biggest number

25 cent and 10 cent make 35 cent

that's 2 coins (25 and 10 coins)

smallest number is 2

differcen between largest and smallest=7-2=5

5 is the answer
