The hourly profit made when selling the product at price P and the product is displayed at height H [cm] on the shelf.

1	grocery(P=3.46, H=150)

`P`	the selling price of the product. The default amount, if unspecified, is €3.46.
`H`	the display height of the product, as measured from the ground up. The default value, if unspecified, is 150cm.

This function simulates the hourly profit in a grocery store of selling a particular product.
Two factors can be adjusted by the user to determine the optimum:

P: The selling price of the product (must be a positive value).
H: The height that the product is displayed at (must be a positive value).

Can you determine the best combination of conditions, using a systematic method (i.e. not by trial and error)?

Returns the hourly profit made. Random noise is added for some realism.

# Selling at the default settings of price (€3.46)
# and shelf height (150cm):
grocery()

# Let's try selling for a low price, €2.75,
# and put the product 120 cm off the ground
grocery(P=2.75, H=120)

# What happens if the product is too high
# for the average person?
grocery(P=1.25, H=200)

# Can you find the optimum combination of settings to
# maximize the profit, but using only a few experiments?
