196.有两个table(数字可能不大正确) , 第一个是 unit price per item 1-100: $1; 101-300: 0.75; 301+: $0.5 第二个是 shipping price per order 1-100 $10; 101-200 $15; 300+ $20 然后说第一个人order 400 item in order, 第二个人 order 1st order of 100 items, and 2nd order of 300 items, 问 what is the difference of the price charged between the first and second person. (大概就是这个意思)
请问是1-100: $1; 101-300: 0.75; 301+: $0.5 拿第一个人来说,他的price是100+200*0.75+100*0.5+20 还是400*0.5+20 第二个人的是不是100+100+200×0.75+10+20?
