|When Jimmy Kirk started a new game of Cosmic Armageddon on-line, he
used his initial 6,000 Cosmic Credits to buy six different pieces of game
equipment, including a particle rifle. Each bit of gear cost a different
amount of money, and each was manufactured on a different planet in the game
Cosmos. Given the data below, can you determine how many credits Jimmy
paid for each article and the planet on which it was made?
- The ATT transponder Jimmy bought wasn't his most expensive purchase.
- The article from Phaetonia cost 600 more credits than the gravity boots.
- The stun shield cost 200 more Cosmic Credits than the piece of equipment
manufactured on Airth.
- Jimmy spent 200 more credits on the gear from Delpi than he did for the
article made on Tau.
- The item made on the planet Xenobus cost Jimmy twice as much as the stun
- The least expensive of the six items cost 200 credits.
- The gear from the planet Landesberg cost Jimmy less than the X-Sled did.
- Jimmy spent twice as much for the ATT transponder as he did for the
item made on Delpi.
- Before buying the six pieces of equipment, Jimmy thought of spending 2400
credits on a Numerian shape-shifter but then decided he could do better
in the game by not spending so much for any single piece of gear.
- The most-expensive light glasses available to Cosmic Armageddon
players cost 1000 credits, and Jimmy bought a cheaper pair.
