To find the total number of offices in the building, we can use the fact that 78 offices represent 40% of the total units. Let's denote the total number of offices as x
We know that 78 offices represent 40% of x So, we can set up the equation:
0.40x = 78
To solve for x, divide both sides by 0.40:
x = 78/0.4
x = 195
So, there are 195 offices in the building.
