I can tell you there's more than four combos right now.

jim_thompson5910 · Answer

Yeah there are actually 7 ways to do this

anonymous · Answer

Oh.. o.O i was told ther ewas only 4

jim_thompson5910 · Answer

odd, well here are the 7 ways


2 ones + 1 five + 1 twenty ... 4 bills total
2 ones + 1 five + 2 tens ... 5 bills total
2 ones + 3 fives + 1 ten ... 6 bills total
2 ones + 5 fives ... 7 bills total
7 ones + 1 twenty ... 8 bills total
7 ones + 2 tens ... 9 bills total
7 ones + 2 fives + 1 ten ... 10 bills total


each way adds up to $27 (since you'll get $27 in change)

jim_thompson5910 · Answer

this is just something you do by trial and error

so you would maybe list out a table of combos until you find all the possible combos

anonymous · Answer

Yeah, I found it by trial and error. You just have to hope, I'd imagine, there isn't too many.

anonymous · Answer

two 10, one 5 and two 1
Explanation: 50 less 23 its 27…how many bills the cashier have to gives you

not sure what you're asking here...

jim_thompson5910 · Answer

oh my bad, i somehow had a 20 in there...it should be just 1s, 5s, and 10s

let me fix that real quick

2 ones + 1 five + 2 tens ... 5 bills total
2 ones + 3 fives + 1 ten ... 6 bills total
2 ones + 5 fives ... 7 bills total
7 ones + 2 tens ... 9 bills total
7 ones + 2 fives + 1 ten ... 10 bills total
