# Hard 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 $4455.54.

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

# My solution:

# First, a helper method:
def is_a_multiple_of?(factor, candidate)
  return candidate % factor == 0
end

sum = 0                               # I read this as:
1.upto(999) do |number|               # "From 1 upto 999, for each number,"
  if is_a_multiple_of?(3, number)     # "If the number is a multiple of 3"
