Final answer:
The sum of two numbers is found by adding the two numbers together. In this case, the sum of the two numbers is 4435.
Step-by-step explanation:
The sum of two numbers is found by adding the two numbers together. In this case, the difference between the two numbers is given as 1875. Let's assume the larger number is x. We know that the smaller number is 1280. So, the equation becomes x - 1280 = 1875. Solving this equation for x, we add 1280 to both sides to isolate x, giving us x = 1875 + 1280 = 3155.
Therefore, the sum of the two numbers is 3155 + 1280 = 4435.
