a company uses linear programmming to decide on the production and sales budget that will maximise total contribution and profit for a financial period. The optimal solution involves using all available direct labour hours, for which the shadow price is $4.50 per hour, and machine hours, for which the shadow price is $3 per machine hour. Direct labour is paid $8 per hour.

A .Up to but not including $4.5
B. Up to but not including $9.5
C. Up to but not including $12.5
