__6th POW__There are about 20 potatoes in a 5 pound bag. A restaurant uses about 2 potatoes per order of french fries. They charge $1.25 for an order of fries. How much money does the restaurant take in (for french fries) on a day that they use 400 pounds of potatoes?

__7th POW__Your heart pumps about 5 quarts of blood through its chambers every 60 seconds. A swimming pool (20 ft. x 60 ft.) will hold about 65,000 gallons of water. This represents the amount of blood pumped by your heart in approximately how many weeks?

Byron lives where the people trade goods they produce for other things that they need. He has some fish that he has caught, and he wants to trade them for as many bananas as he can. He also asks around to find out what is being traded and finds out the following:

- Five fish are worth the same as two loaves of bread.
- Six oranges are worth the same as two melons.
- One loaf of bread is worth the same as one banana plus three oranges.
- Four loaves of bread are worth the same as fourteen oranges.

**How many bananas can Byron get with five fish?**
