Elijah just bought a house with a $72,000 mortgage at a 3.13% annual interest rate. How much of a $930 payment will go towards p
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

since we can't see the image, I'm just giving it a try

if it's wrong, it's fine for you to delete it

Step-by-step explanation:

if one of the length is 5.6 units then the other will be 5 units

if one of the length is 4 units then the other will be 7 units

if one of the length is 2 units then the other will be 14 units

if one of the length is 1.86666666667 units then the other will be 15 units

if you're looking of an area, it might be 7 units

and I think that's all I've got

(hope it helps)
