uranmaximum [27]

Answer:

$2076.30

Step-by-step explanation:

In the n-th year, the rent will be ...

an = a1·r^(n-1) . . . . . . . . . r is the year on year ratio: 1+rate of increase

an = 1100·(1.095^(n-1))

Then the rent in the 8th year is ...

a8 = 1100·(1.095^(8-1)) ≈ 2076.30

The rent in the 8th year would be $2076.30.
