问一道很简单的英文应用题
An insurance salesperson,who sold 260 policies last year,has averaged 4 policies per week for the first 8 months of this year.How many policies per week must he average in the remaining weeks in order to equal his performance for last year?
由于告诉的是前8个月,而问又是星期为单位,每个月几个星期又不固定,怎么换算能够达到最高效率?
