Step-by-step explanation:

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
