After presenting the initial results to his manager Ms$.$ Lee, Nathan noticed his model was missing the manufacturing capacity constraints. Additionally, aiming to increase efficiency, Ms$.$ Lee requests including a new constraint about the maximum power consumption in kW for the T$-$Crates in total should not exceed $60000$ kW$.$

Table $3$: Machine$$s capacity in minutes

Machine Capacity in Minutes

Machine $1300$

Machine $2500$

Machine $3450$

Table $4$: Power consumption per minute

Machine Kw per minute

Machine $145$

Machine $260$

Machine $355$

What$$s the minimum possible cost to produce the required units including the new information in the model?
