A building has the same number and size of rooms on each floor. If there are 10 offices on the first 2 floors, then what is the total number of rooms in the 5 story building?

10


20


25


30

Answer 1

10/2=x/5
2x=50
x=25

there are 25 rooms in the 5 story building

Answer 2

25 because if there are 10 rooms on 2 floors that means there are 5 on each floor. So thats 5 rooms per floor and there are 5 floors so its 5 times 5 which is 25!!
25 is the answer
