In a cashbox filled with $1, $5, $10, and $20 bills, there is a total of $400. The number of $5 bills was 4 times the number of $10 bills and the number of $1 bills was 10 more than the number of $10 bills. There are four $20 bills. How many bills of each type were in the cashbox?

The answer is 26 to 1

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?
