Answer:
$442.1 per month
Step-by-step explanation:
Lilly took 80/20 mortgage to buy house costing $ 100000
80% × 100000 = 80000 for the first at 4.75%
80000 × 4.75% = 80000 × 0.0475 = $ 3800 as interest per year,
20% × 100000 = 20000 for the second mortgage
20000 × 7.525% = 20000 × 0.07525 = 1505 as interest per year
add the first interest and the second interest
3800 + 1505 = 5305
divide the answer by 12 months to find the monthly payment
5305 / 12 = $442.1 per month
