now we know
y+3=0
x-2=0
therefor
y=-3
x=2
Given:
Total price : 107,820
down payment 15% of the total price.
financing the remainder at 6.5% for 25 years.
How much is she financing? She will finance 85% of the total price.
107,820 * 15% = 16,173
107,820 - 16,173 = 91,647
or
107,820 * (100-15)% = 107,820 * 85% = 91,647
