Please answer each question with step by step explanation. Thank you

Two products (Q and T) are made on the same machine. The set-up time is 90 minutes when you change from one product to the other. The weekly production quantities of Q and T must be in the proportion of 5 to 2. Production times per unit 3 minutes for Q and 5 minutes for T. Assume 40-hour workweek. Your aim is to maximize weekly production. How many units of Q and T can you produce in one week? 11. What % of the production time should be allocated to Q? a) 80 b) 40 c) 20 d) 60 12. What is the nearest to the maximum production time per week [in minutes]? a) 2200 b) 2100 c) 2400 d) 2300 13. How long should we allocate time to produce Q, in hours and minutes? a) 23:10 b) 23:06 c) 21:36 d) 22:50 14. What is closest to the weekly production of Q? a) 460 b) 420 c) 440 d) 400 15. If we make the final product by assembling 5Q's and 2T's, what is closest to the number of final products we can make? a) 150 b) 200 c) 90 d) 230
