Question

Last year a farmer dug

Answer 1

Answer:  935 tons

Explanation:

We'll add the last two values to get the amount dug this year.

2786+2862 = 5648

So the farmer dug 5648 tons of potatoes this year.

Subtract that result from the first value given

6583 - 5648 = 935

The farmer dug 935 more tons last year compared to this year.

In other words, the amount has dropped by 935 tons when going from last year to this year.
