please help I've gotten the wrong answer on Chegg twice already

Manager Chris Channing of Fabric Mills, Inc., has developed the forecast shown in the table for bolts of cioth. The figures are in hundreds of bolts. The department has a regular output capacity of 195(00) bolts per month, except for the seventh month, when capacity will be 210(00) bolts. Regular output has a cost of $11 per hundred bolts. Workers can be assigned to other iobs if production is less than reqular. The beainning inventorv is zero bolts. a. Develop a chase plan that matches the forecast and compute the total cost of your plan. Overtime is $24 per hundred bolts. Regular production can be less than regular capacity. (Negative amounts should be indicated by a minus sign. Leave no cells blank - be certain to enter "O" wherever required.) b. Would the total cost be less with full regular production each period with no overtime, but using a subcontractor to handle the excess above regular capacity at a cost of $26 per hundred bolts? Backlogs are not allowed. The inventory carrying cost is $2 per hundred bolts. (Round your Average inventory values to 1 decimal place. Negative amounts should be indicated by a minus sign. Leave no cells blank - be certain to enter " 0 " wherever required.)
