So first we were to told that the sum of 2 numbers add to 19

a+b=19---------(1)

and they subtract to 5

a-b=5-----------(2)

These are two simultaneous equation and can be solved by elimination:

(1) + (2):

(a+b)+(a-b)=19+5

2a=24

a=12

12+b=19

b=7

So the two numbers are 12 and 7

Mamont248 [21]

Answer: $742.20

Step-by-step explanation:

The payments will be divided between an interest and a principal payment.

The interest payment will be based on the balance at the beginning of the period and the rest of the payment will be the mortgage.

Balance at beginning of period = $72,000

Interest payment = (3.13% * 72,000) / 12 months

= $187.80

Amount going towards principal:

= Total payment - Interest payment

= 930 - 187.80

= $742.20
