Question

A 1-bedroom apartment on the 10th floor of the Downtown Apartment Complex rents for $390 per

month. A 1-bedroom apartment on the 15th floor rents for $440 per month. If the price of the apartment
goes up in equal increments as the floor number increases, what is the monthly rate for a 1-bedroom
apartment on the 34th floor?

Answer 1

630

explanation

it's a graph question in the form of a word problem

question says if

(10, 390) & (15, 440) then (34, y)?

if x = 34 then what is y

get slope

m = (440 - 390) / (15 - 10) = 10

get graph

y - y1 = m(x - x1)

y - 440 = 10(34 - 15)

y - 440 = 190

y = 630
