The answer is 7 R 4! hoped this helps!
Let
x-----> the purchase price of the house
we know that
1) Marika paid 
of the purchase price of the house with a loan
2) Marika paid the remaining 
of the purchase price with her savings
3) represent the 
of the purchase price
so
Solve for x
Divide by 
both sides
therefore
<u>the answer is</u>
the purchase price of the house is 
((7 + 5)^2) / (4 * 3 + 9) =
(12^2) / (12 + 9) =
144 / 21 reduces to 48/7 or 6 6/7
Multiply both sides of the equation by 12. Move the variables to the left-hand side and change its sign. Move the constant to the left-hand side and change its sign. Collect like terms. Add the numbers. Divide both sides of the equation by 12.
1/2 x - 5= - 1/2 x + 19/4
6x -20= - 6x + 57
6x + 6x= 57 + 20
12x= 57 + 20
12x= 77
ANSWER
x = 77/12
Alternative Form .
x = 6 5/12, x= 6.416
160 is 100% of 160, 480 is 4 times that. So 400%
