Good evening I was wondering if you could show guidance on this question:

A local newspaper distributes this list of advertising rates on its rate card: No. of column-inches Advertising rate per column-inch 035,000 $2.00 35,00170,000 $1.90 70,001100,000 $1.75 100,001150,000 $1.65 More than 150,000 $1.50.

Using the figures from question 1, what if the advertiser actually had used 68,000 column-inches of advertising during the year? Did the retailer earn the contractor a rebate, or a short rateand if so, how much? Again, please show your calculations and clearly indicate your answer.
