Margaret [11]

Answer:

$122.04
36.94%

Step-by-step explanation:

a) The amount of concern is ...

(total interest)/(number of payments) = interest/payment

$14,644.95/120 ≈ $122.04 . . . . amount of interest per payment

b) The ratio of concern is ...

(total interest)/(total payments) × 100% = 14,644.95/39,644.95 × 100%

9 is the difference between two numbers, and their sum is 31. Find the numbers.

algol [13]

Answer:

The first number is 20, the second one is 11

Step-by-step explanation:

Let the first number be x and the second number be y

Since it says "9 is the difference between two numbers", the first equation will be x-y=9

It also says that "their sum is 31". That means the second equation will be x+y=31

here are the two equations:

x-y=9

x+y=31

You can solve this any way you like, but I'll show elimination

add the two equations

x-y=9

x+y=31

2x=40

divide by 2

x=20

Substitute 20 as x in one of the equations

20+y=31

subtract 20 from both sides

y=11

That means the two numbers are 20 and 11

Hope this helps!
