Additionally, the company will discontinue the practice of shipping each phone with a $250-$page user manual and instead will make the manual available online. These changes will result in a lighter but more difficult package for shippers to handle. The weight of each packaged phone has dropped from $1\mathrm{.}2$ pounds to $0\mathrm{.}5$ pound as a result of these changes; and the freight classification has worsened from $55$ to $70.$ Use Table $15\mathrm{.}2$ to calculate the difference in Microtech$$s monthly shipping charges if the company ships $10,000$ phones per month.
