Suppose you rent apartments in a large apartment complex. Currently there are 90

Question

apartments being rented at a rent of $1300 per month. Evidence shows that for every
increase of $25 per month in rent, there will be 1 additional unit unrented.

(a) U is the number of units rented and R is the amount of rent per month, find a
linear relationship of U in terms of R.

Answer 1

so mainly i relly don't know so good luck

Answer 2

Thanks for stopping by, bob...

If the number of $25 increases is x, then

U = 90-x
R = 1300+25x

So, that means

x = 90-U
x = (R-1300)/25

Equate the two expressions and you have

90-U = (R-1300)/25
U = 90-(R-1300)/25
or
U = 142 - R/25
