a) $107,920

b) yes

c) $668.24

d) 187,357.75

e) $52,457.75

Step-by-step explanation:

a) 20% paid, 100-20 = 80% mortgage

134900 × 80/100 = 107,920

b) 107,920 = mortgage

Mortgage including interest:

107920 × 1.0425 = $112,506.6

Income = 20 × 68450

= $1,369,000

Since her Income is greater, she can afford it.

c) 6.192 × 107920/1000

= 668.24064

d) (668.24064 × 20 × 12) + (20% of 134900)

= 187,357.7536

e) 187,357.7536 - 134900

= 52,457.7536
