Answer:
The number of houses on Algebra Avenue are 76 houses
Explanation:
The given information are;
Buildings on Algebra Avenue in Mathpolis = 2 or 3 stories high
Total number of stories = 95 + Total number of houses
The number of two-story houses = 3× The number of three-story houses
Let the number of three-story houses = X
Therefore, the number of two-story houses = 3 × X
Total number of stories = 3×X + 2×3×X = 9·X
The total number of houses = X + 3 × X = 4·X
Given that, the total number of stories = 95 + Total number of houses, we have;
9·X = 95 + 4·X
9·X - 4·X = 95
5·X = 95
X = 95/5 = 19
X = 19
The total number of houses = 4·X
Therefore, the total number of houses = 4 × 19 = 76 Houses.
