Answer:
The increase in rent is 20%.
Step-by-step explanation:
Last year rent of an apartment on the Gold Coast for a weekend was $400.
This year it costs $480
Now we calculate the increase of rent
( 480 - 400 ) / 400 = 80 / 400 = 0.20
To convert into percentage we multiply it by 100 = 0.20 × 100 = 20%
The increase in rent is 20%.
As per linear equation, the increase in rent of the apartment is 20%.
What is a linear equation?
A linear equation is an equation that has the highest power of the variable as 1.
Given, it costs 480 to rent an apartment this year.
Last year it was cost $400 for the same apartment .
Therefore, the increase in rent of the apartment is
= $[tex](480-400)[/tex]
= $[tex]80[/tex]
Therefore, the percentage increase of rent of the apartment is
[tex]= \frac{(80)(100)}{400}[/tex]%
[tex]= 20[/tex]%
