Microtech Incorporated has decided to package its cell phone in a smaller, recyclable package. Additionally, the company will discontinue the practice of shipping each phone with a 250-page user manual and instead will make the manual available on line. These changes will result in a lighter, but more difficult package for shippers to handle. The weight of each packaged phone has dropped from 1.2 pounds to 0.5 pounds as a result of these changes and the freight classification has worsened from 55 to 70. Use Table to calculate the difference in Microtech€™s monthly shipping charges if the company ships 10,000 phones permonth.
