Question

a cashier has a total of 26 bills made up of tens and hundreds the total value is 1610 how many hundreds and tens does she have?

Answer 1

Let the tens be x.

Therefore the hundreds will be (26 - x).

Since they both total to 26. x + (26 - x) = 26

10*x + 100*(26 - x) = 1610

10x + 2600 - 100x = 1610

10x - 100x = 1610 - 2600

-90x = -990

x = -990/-90

x = 11.

So the 10s are x =11, the 100s are (26 -11) = 15

11 tens bills and 15 hundred bills.
