$3.$ Management does not use an economic criterion, like EOQ, to determine planting quantity. Rather, they have stated that they want to plant a minimum of a year$$s worth of high$-$volume and two years$$ worth of low volume trees at a time. The idea is to order the year$$s supply target plus an amount needed to make up the difference between the minimum and current inventory position. For those tree types that are below the minimum level $($calculated in part $2),$ calculate a proposed planting quantity. Create an additional column in the table for the proposed planting quantity.
