The cost of building a certain house in an area is 100,000 more than the construction cost of each of the houses in the area.  But it sells for 1.5 times as much as the other houses, which sell at $320,000 each. How much more profit is made by spending the extra money to build?
The house cost 320,000*1.5=$<<320000*1.5=480000>>480,000
So it is worth 480,000-320,000=$<<480000-320000=160000>>160,000 more than other houses
So the profit is 160,000-100,000=$<<160000-100000=60000>>60,000 more
#### 60,000
