Answer 2

Answer:

The average farm size was 400 acres in 1950.

 

Explanation:

Number of years = 1980 – 1920 = 60

Total growth in farm size between (1920-1980) = 700 acres

Average yearly growth in farm  size (x) = (700 acres – 100 acres)/ 60 = 600/60 = 10 acres

Therefore:

10 acres X 30 years = 300 acres

1920 + 30years = 1950
