Ralph Chase plans to sell a piece of property for ​$170000. He wants the money to be paid off in two ways monica ​short-term not
natima [27]

Answer:

The amount of 12% note is $90,000

The amount of 9% note is $80,000

Step-by-step explanation:

Missing word <em>"The amount of the 12% note is $ and the amount of the 9% note is $"</em>

<em />

Selling price = $170,000

Let x be the amount of money paid short term, therefore the amount of money paid long term is (170000 - x)

Given total annual interest = $18,000

Total annual interest = Interest due to short term (x) + interest due to long term (170000 - x)

18,000 = 0.12x + 0.09*(170000 - x)

18,000 = 0.12x + 15,300 - 0.09x

18,000 = 0.03x + 15,300

0.03x = 18,000 - 15,300

0.03x = 2,700

x = 2,700/0.03

x = 90,000

So, the amount of 12% note is $90,000

So long term paid money = $170,000 - $90,000 = $80,000

So, the amount of 9% note is $80,000

Write and solve an equation to answer the question.
velikii [3]

Answer:

3500

Step-by-step explanation:

An average is just the total attendance numbers / the number of performances.

Let’s let the number of people in the third show be equal to x so we can write this as a formula, it’s easier to read. x is just "some number we don’t know"

The average is

Average=Total attendance/3

So

3000=(2580+2920+x)/3

So let’s multiply by that 3 on both sides, make x easier to find

Average*3=2580+2920+x ( * means multiplied)

The average is 3000

So

2580+2920+x=3000*3

2580+2920+x=9000

Then we subtract those other attendances to get x on its own.

x=9000-2580-2920

x=3500

I hope you have understood
