# This is a dataset about products, their inventory levels
# and unit costs at a company
productNames = c("x01","x02","y25", "y39", "z33", "z47", "z59")
inventoryLevels = c(1200, 1450, 1100, 900, 550, 730, 850)
product UnitCosts = c(11.50, 9.50, 13.00, 20.50, 25.00, 42.00, 35.00)
# 1) List first 3 product names
# 2) List inventory levels of product 2, 5, and 7
# 3) List cost of all products except 3 and 6
# 4) The company decided to discontinue product "z33". So, delete
# this product's name, inventory and cost information from the
# the dataset.
# 5) The company decided to make a new product called "x10" with
an initial inventory level of 100 and unit cost of 45.00 dollars.
Add this new product's information at the end of the dataset.
#
# 6) The company needs to know how much money is tied at the
inventory (ie. value of the inventory).
For this calculation, you need to write a long equation
multiplying each product's inventory level by the unit cost,
and adding up for all products. Print inventory value at the end.
HINT: invValue = inv1 * cost1 + inv2 * cost2 + ...
