Answer:
$1,369.25
Explanation:
Mr. and Mrs. Wong purchased their new house for $350,000.
They made a down payment of 20%
Down payment = 20% of 350000
= $70,000
Loan amount, P = $350,000 - $70,000
= $280,000
Rate of interest, r = 4.2% or 0.042
Time, t = 30 years
Number of period, n = 12 ( monthly )
Formula:
![E=(P\cdot (r)/(n))/(1-(1+(r)/(n))^(-n\cdot t))](https://img.qammunity.org/2020/formulas/mathematics/college/tn0pjxq4arx5ds27gl1k37e39igglrypte.png)
Substitute the values into formula
![E=(280000\cdot (0.042)/(12))/(1-(1+(0.042)/(12))^(-12\cdot 30))](https://img.qammunity.org/2020/formulas/mathematics/college/o7g4ypobeqqth15me207ko1nyhkhgmr1aj.png)
E = $1,369.25
Hence, The monthly payment for their mortgage will be $1,369.25
