Name on billboard

Description

If you can't sleep, just count sheep!!

Task:

You can print your name on a billboard ad. Find out how much it will cost you. Each character has a default price of £30, but that can be different if you are given 2 parameters instead of 1 (allways 2 for Java).

You can not use multiplier "*" operator.

If your name would be Jeong-Ho Aristotelis, ad would cost £600. 20 leters * 30 = 600 (Space counts as a character).

My Solution

def billboard(name, price = 30)
  name.size.times.inject(0) {|sum, _|  sum += price}
end

Better/Alternative solution from Codewars

def billboard(name, price = 30)
  name.size / (1.0 / price)
end
