Answer:
$1,369.25
Step-by-step 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:
Substitute the values into formula
E = $1,369.25
Hence, The monthly payment for their mortgage will be $1,369.25
There are 90 4-digit palindromes
<h3>What are palindromes?</h3>Palindromes are numbers whose reverse is the same as the original number
<h3>How to determine the count of 4-digit palindromes</h3>Since the digit is 4, then
- The first digit of the palindrome can be any of 1 to 9 (i.e. 9 digits)
- The second digit can be any of 0 - 9 (i.e. 10 digits)
- The third digit must be the second digit (i.e. 1 digit)
- The last digit must be the first digit (i.e. 1 digit)
So, the total number of digits is:
Evaluate the product
Hence, there are 90 4-digit palindromes.
