Question

A landlord charged $865 per month to rent an apartment in 2010. The rent increased at a constant rate and reached $1065 per month in 2018. Estimate the monthly rent in 2021

Answer 1

Explanation:

1065 = 2018

865 = 2010

-___________

200=8

200/8 = $25/per year increase

since

2018 = 1065

2021-2018 = 3 years

$25*3 = $75 increase

So 2021= 1065+ 75 = $1,140
