Whilst practising "Adding and subtracting decimals word problems", I got the following question:
"On a sunny morning, Nadia rode her bicycle to a farm that sold bags of kiwis for $9.95 each and bags of pomegranates for $5.35 each.

Nadia decided to buy a bag of kiwis and a bag of pomegranates .

How much did Nadia need to pay for her produce?"

I first entered the value $15.30, and was told it was wrong. The accepted answer was 15.30. This is not clear for someone who hasn't clicked on the 'Show acceptable answer formats' link.
