Responses
A 32
Since 80 houses in total, and we know that some have a chain link fence and some have a privacy fence, the number of houses with no fence in the backyard can be calculated by subtracting the number of houses with a chain link fence and the number of houses with a privacy fence from the total number of houses:
Total houses - (chain link fence houses + privacy fence houses) =
80 - (20 + 28) =
80 - 48 =
32
Therefore, 32 houses have no fence in the backyard.
