Answer:1000 bills = 7

500 bills = 19

Step-by-step explanation:x=number of 1000 bills

y= number of 500 bills

(you can even invert them, no problem)

the system is

x + y = 26

1000x + 500y = 16500

therefore

x=26-y

using this value in the next equation

1000*(26-y) + 500y = 16500

26000 – 1000y + 500y = 16500

-500y = – 9500

y=9500/500= 19

x=26-19= 7

Answer:you would divide 16500 by 500 and 1000

Step-by-step explanation:so i got 12 and 16.5
