He got 30% correct. To get this answer, you would divide 27 ÷ 90 and get 0.3. Then you would convert 0.3 into fraction form, which is 30%.
To find this you would do 800 + 15x where x is the amount of years.
For 9 years it would be 800 + 15(9) which is 800 + 135.
At the end of 9 years, the apartment's rent would be $935. I hope that's utilities included because... yikes...
