Answer:
$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.
