The Chandler's Crates

The chandler of bitwick has finished her winter pour and needs the market takings worked out before dawn.

Candles travel to market in crates. A crate holds exactly size candles and, when full, sells for crate coins. Any candles left over after the crates are filled are sold one at a time for spare coins each.

Write crateTakings(candles, size, crate, spare), which returns the total number of coins taken: the number of completely full crates multiplied by crate, plus the number of remaining candles multiplied by spare.

  • candles is an integer, 0 or greater.
  • size is an integer, 1 or greater.
  • crate and spare are integers, 0 or greater.
  • The return value is an integer.
  • simple arithmetic

examples

  1. case 1candles of 30, size of 12, crate of 100, spare of 7242 — two full crates (200 coins) and 6 loose candles (42 coins)
  2. case 2candles of 7, size of 12, crate of 100, spare of 749 — no crate can be filled, so all 7 are sold loose
  3. case 3candles of 24, size of 12, crate of 100, spare of 7200 — two full crates and nothing left over
