Answer:
Step-by-step explanation:
Let the number of floors = x
Number of apartments per floor = 4x
4x *x = 100
4x² = 100
x² = 100/4
x² = 25
x =√25
x = 5
Number of apartments on each floor = 4*5 = 20
Let x be the cost of gum 20 years ago.
3x - 3 = 75
3x = 78
X = 78/3
X = 26.
So the write answer is A) 3x - 3 = 75.
