Renauld has to pay 2 percent in closing costs and 14 percent for the down payment on a purchase of $170,500. over the life of his loan, he will pay $163,021.87. what is the total cost of his house? a. $166,431.87 b. $186,891.87 c. $190,301.87

Renaud has to pay 2 percent + 14 percent = 16 percent initial costs

We can establish a proportion:

If 100% is => $170,500

Then 16% =>  $C costs

$C = 16 x $170,500/100 = $27,280 initial costs

Total cost = $163,021.87 + $27,280 = $190,301.87

Answer : C.) $190,301.87

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
