The average price of a home sold in the United States in 1980 was $47,200 and the average income was $21,063. In 2018, the average price for a home was $380,000, and the average income was $63,179.1) Find the relative change in housing prices from 1980 to 2018.

The relative change in housingbprices from 1980 to 2018 is 705.08475

Step-by-step 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

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
