700 plus 700 plus 700 equal?

Answer 1

700 + 700 + 700 = 2100
As the question is stated, the first two numbers are dimensionless, and only the third number has dimensions of dollars. Very technically then, the sum is: 1,400 + $700. However, we can reasonably surmise that the questioner intended for each of the three numbers to have the same dimensions. If this is true, then the sum is: $700 + $700 + $700 = $2,100
