What amount is left? 45¢ Which coin represents the greatest amount? a quarter 25¢ +10¢= 35¢ 35¢ +10¢= 45¢ So, one combination for $6.45 isone 5-dollar bill, one 1-dollar bill, one quarter, two dimes.

  4. +10¢ +10¢ +10¢ +5¢ 3-2 Lesson 4-2 Example 4 Solve Now represent $6.45 using a different combination of bills and coins. $6=six 1-dollar bills 45¢ = 10¢ 20¢ 30¢ 40¢ 45¢ 45¢ = 10¢ 20¢ 30¢ 40¢ 45¢ = 10¢ 20¢ 30¢ 45¢ = 10¢ 20¢ 45¢ = 45¢ = 10¢ A second combination of bills and coins issix 1-dollar bills, four dimes, one nickel.
