How many months did the research take? ** The research ended up taking 5*10=<<5*10=50>>50 months
How many months did the research take? ** So he paid for expensive research for 50-5=<<50-5=45>>45 months
How much did each month of research cost? ** Each month of research at the cheaper stage cost 100,000/5=$<<100000/5=20000>>20,000
How much did each month of research cost? ** So the more expensive research cost 20,000*1.5=$<<20000*1.5=30000>>30,000
How much did his research cost? ** So that research cost 45*30,000=$<<45*30000=1350000>>1,350,000
How much did his research cost? ** So the total cost was 1,350,000+100,000=$<<1350000+100000=1450000>>1,450,000
