Hey. Let me help you on this one, Jordynahaines.
In order for us to get a clearer view of the problem, let's break it down into smaller pieces.
Person paying us has a capital of $20 dollars, and we are tendering $18.32 from the whole of twenty. This means we will need to form a subtraction operation; however, it's might be a little bit tricky at first, especially if you are new to subtraction with decimals.
It's important to remember that twenty as a number is the same as "20.00". This will help us to get the final answer by subtraction.
Now let's actually perform the operation.
As you can see, our remainder is $1.68, meaning that your correct choice will be the first one.
Answer: $1.68 should be given back.
