<human>:  Mike decides to develop a plot of land. He bought 200 acres for $70 per acre. After development, he sold half of the acreage for $200 per acre. How much profit did he make?
<bot>: How much did Mike buy the land for? ** He bought the land for 200*70=$<<200*70=14000>>14000
How many acres did Mike sell? ** He sold 200/2=<<200/2=100>>100 acres
How much did Mike get from selling this? ** He got 100*200=$<<100*200=20000>>20,000 from selling this
How much profit did Mike make? ** So he made a profit of 20,000-14,000=$<<20000-14000=6000>>6,000
