Mrs. Chatman buys popcorn for $4.97 and a coke priced at $3.43. She gives the cashier a $20 bill. How much change should she receive? right answer please ill give brainliest

$11.60 (see below)

Step-by-step explanation:

First, you need to find the total cost of the two items bought:

Add the two decimals together:

      1    1

  $ 4 . 9 7

+ $ 3 . 4 3

  $ 8  . 4 0

So the total cost was $8.40.

If this was paid by $20, then you will have to subtract the cost:

     1  9  10  

  $ 2 0 . 0 0

– $    8 . 4 0

  $ 1  1 . 6 0

So the change was $11.60.
