The toll for an auto mobile to cross a certain bridge it 40 cents. A machine in an EXACt CHANGE lane will accept any combination of coins that has a total value of 40 but will not accept pennies. In how many ways can a driver pay the toll in the EXACT CHANGE lane???Another math problem(please show how you solved it)?
I live in England so bear with me! Presuming the only coins you can use are, 25cent, 10cent and 5cent..
25c 5c 5c 5c
25c 10c 5c
10c 10c 10c 10c
10c 10c 10c 5c 5c
10c 10c 5c 5c 5c 5c
10c 5c 5c 5c 5c 5c 5c
5c 5c 5c 5c 5c 5c 5c 5c
