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 b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
