Connor went to the bank with the twenty dollar bill he got for his birthday. If he wanted the bank to exchange the twenty
dollar bill for other bills (no coins), what are all the different
ways they could give him his twenty dollars back?
PLEASE HELP THIS NEED TO BE DONE IN 45 MINUTES

Connor could give $50 and receive five $10 bills equaling $50 .

he could give $50 and receive two $20’s and two $5 bills = $50

give $50 and receive fifty $1 bills = 50

give $50 and receive 10 $5 bills = 50

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
