Abby must plan for her lemonade stand next Saturday. She can stock (lemons, sugar) a small amount (cost = $10) or a large amount (cost = $20) of inventory. But the payoff depends on the weather. The revenues are shown below:

	no rain	rain
stock - small amount	25	20
stock - large amount	45	20

The probability of raining on the next Saturday is 0.3. Any leftover stock is worthless.

What is the expected value of profit if she stocks a large amount?

(Note: profit = revenue - cost)
