Could you please give me step by step instructions on how to solve this word problem?

Jinny is canning pickles and needs 5 cups of 5% vinegar. She has a container full of 4% vinegar and a container full of 8%. How much of each kind should she mix to obtain her 5 cups of 5% acidity? Round your answer to the nearest hundredth.

Thank you(Wink)
