Imagine the digits are A and B (for the mystery number AB)
A + B = 8 [1st equation]
AB - BA = 18
A*10 + B - 10*B - A = 18
9A - 9B = 18 / divide everything by 9
A - B = 2 [2nd equation]
If you add the two equations you get
2A = 10
A = 5
So B = 8 - 5 = 3
So the number is 53
L=9 in
W=4,25 in
A=L·W
A=9·4,25
A=38,25 in²
<em>A≈38 in²</em>

Answer:
A) $1350
B) $5850
C) $162.50
Step-by-step explanation:
A) The interest is given by the formula ...
I = Prt
where P is the principal amount, r is the interest rate, and t is the number of years.
I = $4500×0.10×3 = $1350
The interest owed is $1350.
__
B) At maturity, the principal and interest are due. That amount is ...
$4500 +1350 = $5850
The maturity value is $5850.
__
C) If the maturity value is paid in 36 equal monthly installments, each is ...
$5850/36 = $162.50
The monthly payment is $162.50.
