So if I produce one unit it costs me c; if I produce two units it costs me 2c; if I produce 100 units, it'll cost me 100c and if I produce 0.735 units that costs me 0.735c.

生产1单位的产品成本是c,如果生产2单位成本就是2c,如果我生产100单位成本就是100c,如果生产0.735单位就是0.735c

Just to remind those people who are not Economics Majors what that means, it means if I produce 1 unit then it costs me C to produce, if I produce two units it costs me 2C, 100 units a 100C and so on.

顺便提示一下那些,非经济专业的同学这表示什么意思,它表示生产1单位产品需要消耗C成本,如果生产2单位,需要的成本是2C,100单位需要100C,以此类推
