A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Amount of water reservoir can hold = 400400400 million gallons of water ≈ million gallons
Estimated days will drainage take = 252525 days ≈ days
Then the maximum rate of drainage, in millions of gallons per day is
⇒
⇒
Hence we can conclude that the maximum rate of drainage, in millions of gallons per day is 16 millions of gallons per day.

Best Food Store is offering the same size box of
Cocoa Blast at a price of $3.50 for two boxes.
Which offer gives you the most cereal for your
money?
Answer:
The Friendly Food Store's sale.
Step-by-step explanation:
Say you were to get 10 boxes of cereal. We would use this to figure out which one costs less.
Since the Friendly Food Store is offering 5 for 8.25, we would multiply the amount of money by two to get 10.
8.25 x 2 = $16.50
The Best Food Store is offering 2 for 3.50. The same would apply here for the equation, but we would multiply the amount by 5.
3.50 x 5 = $17.50
Thus you would find out that the sale at the Friendly Food Store would give you the most cereal for your money.
