After developing her $2020?$ ?forecast, Jamie Favre gets a visit from $?$ ?Cheeznax's production $?$ ?manager, Mark Mobley. Mark $?$ ?says, "I think the forecast is $?$ ?fine, but I really need estimates of demand broken out by product type. In other $?$ ?words, how much of each $?$ ?month's demand do we think will consist of cheese $?$ ?balls, cheese $?$ ?nachos, and cheese potato $?$ ?chips?" Using the $2019$ ?sales results and the $2020$ ?adjusted forecast $?$ ?results, develop a forecast for each product in each month of $2020.$ ?The sum of the individual product forecasts should equal the monthly total sales forecast. $?(?$ Hint: Use the $2019$ ?figures to estimate what percentage of demand is accounted for by each product $?$ ?type. $)$
