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 
Let’s say it takes time t hours for the interception.
In that time the carrier travels 28t nm west and the helicopter 130t nm.
Now we use the sine rule to find the angle x which lies between the distance 175 and 130t.
sin(x)/28t=sin35/130t. So sin(x)=28sin35/130=14sin35/65=0.1235 and x=7.0964 degrees.
Therefore the helicopter should use a bearing of 35+7.0964=42.0964 degrees north of east or 47.9 degrees east of north approx.
