Can someone tell me how to solve this?
drake is purchasing a home for $249,000. he makes a 30% down payment and obtains a 25-year fixed rate mortgage loan at 5% annual interest. his monthly payments are $1,018.94. he pays an intangible tax of 0.4%. which of the following is the total cost of principal, interest, down payment, and intangible tax?
1)
$305,682.00
2)
$381,079.20
3)
$306,379.20
4)
$381,378.00
i chose 1 as the answer and it said it was wrong. it said 2 is the right answer but i don't know how they found it.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

3 is greater then both of those numbers
