Explanation:

Problem 1:

Step1: Identify the operation

To find the birth year, we subtract the age from the current year (2007).

Step2: Perform the subtraction

Birth year = 2007 - 75 = 1932.

Step1: Identify the operation

To find the average bushels per acre, we divide the total bushels by the number of acres.

Step2: Perform the division

Average = 7000 / 50 = 140.

Step1: Recall the conversion

1 yard = 3 feet.

Step2: Calculate the percentage

Percent = (1 foot / 3 feet) 100% = (1/3) 100% ≈ 33.33%.

Answer:

1932
