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 the largest and the smallest number of coins he can use to pay her ???????
The lowest number of coins he can use is 2 (a quarter and a nickel) the highest number of coins he could use is 7 (seven nickels) the difference between the largest and smallest amount is 5 because 7-2=5
