Answer:

2.38%

Explanation:

In January 2017 the average house price in an area was $279,400

In January 2002 the average house price was $196,300

Therefore the annual increase in selling price can be calculated as follows

t = 15

= ($279,400/$196,300)^1/15 -1

= 1.42333^0.06666 -1

= 1.02378 -1

= 0.02378 ×100

= 2.38%

Hence the annual increase in selling price is 2.38%
