Answer:

1680 ways

Step-by-step explanation:

Permutation has to do with arrangement

If a contractor builds homes of 8 different models and presently has 4 lots to build on, the number of ways he can arrange his homes is expressed as;

8P4 = 8!/(8-4)!

8P4 = 8!/4!

8P4 = 8*7*6*5*4!/4!

8P4 = 8*7*6*5

8P4 = 1680

Hence the can arrange his homes 1680 ways
