    想問樓主係咪打錯題目。因為production cost一個都要$80,(b) part o既total cost 又點可能係$10噤少?一個手袋都造唔到出o黎啦

    其實production cost 係咪$0.80先o岩?如果係,答案如此

    a)

    Total cost

    = fixed cost + production cost

    = C + 0.8x

    b)

    Since total cost is $ 10.00 and the fixed is $ 2.800, we have

    10 = 2.8 + 0.8x

    7.2=0.8x

    x= 7.2/0.8

    x=9

    hence, the number of hangbag produced is 9
