# Ruby creates local variables called first_name and last_name and
# assigns the inputs (or arguments) into them
# The technique above is called "string interpolation".
# When you have a double-quoted string, you can inject
# ruby expressions into it by wrapping them with #{}
# It's shorthand for this:
# puts "My name is " + first_name + " " + last_name + "."

# Challenge

# Based on the data stored in the shopping_cart, sales_tax, and
# params variables below, write code that prints out the customer's total, including
# estimated sales tax, based on the shipping address they entered. Your code should
# work even if the values of the data change.

# Your output should look like this:
#  Your total with tax is $7808.06.

# shopping_cart = [
#   {'name' => "iPad 2", 'price' => 499, 'quantity' => 2},
#   {'name' => "iMac 27", 'price' => 1699, 'quantity' => 3},
#   {'name' => "MacBook Air 13", 'price' => 1299, 'quantity' => 1}
#   ]

# sales_tax = {"IL" => 0.115, "IN" => 0.09, "MI" => 0.06, "WI" => 0.056}

# params = {
#   'name' => "Patrick McProgrammerson",
#   'address1' => "222 W Merchandise Mart Plz",
#   'address2' => "Suite 1212",
#   'city' => "Chicago",
#   'state' => "IL",
#   'zip' => "60654"
#   }

# Hint: First try doing it yourself by hand, and notice the steps you are taking.
# You will have to translate these instructions into Ruby.
