Answer 1

Answer:

There are 4 $5 bill and 2 $1 bills.

the answer will be D.

make equations from given information:

• x + y = 6

• x + 5y = 22

Variable:

Let $5 be y and $1 be x.

solve them simultaneously:

22 - 5y = 6 - y

22 - 6 = - y + 5y

16 = 4y

y = 4

solve for x:

x + y = 6

x + 4 = 6

x  = 6 - 4

x = 2
