Analysis: We can find out how much a suit (1 shirt and 1 pants) costs first, and then sell three shirts and two pants for 604 yuan to find out how much a suit costs.

Solution: (604+566)÷5=234 (yuan)

604—234×2= 136 (yuan)

234— 136=98 (yuan)

A: Every coat 136 yuan, and every pair of pants/98 yuan.
