Answer:
The relative change in housingbprices from 1980 to 2018 is 705.08475
Explanation:
In 1980, the average price of houses was $47,200
In 2018, the average price of houses was $380,000.
The relative change in housing prices from 1980 to 2018 = [(current prices) - (old prices)]/(old prices) × 100
= (380000 - 47200)/47200 × 100
= 332800/47200 × 100
= 7.0508475 × 100
= 705.08475
