4. Two friends are looking to rent an apartment. They have two places in mind, and are deciding
which place is cheaper. The first apartment complex charges a security deposit of $200 and a
monthly rental cost of $600. The second complex charges $600 for a security deposit and a monthly
rent of $500. How many months would the friends need to rent the apartment for the costs of the
two apartments to be the same?

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
