Answer:

the number of single room is 27 and the number of double room  is 53

Step-by-step explanation:

Let x is the number of single room

Let y is the number of double room

We know that:

x + y = 80 <=> x = 80 -y (1)

80x +90y= 6930 (2)

Substitute (1) in (2) we have:

80 (80 - y) + 90y = 6930

<=> 6400 - 80y +90y = 6930

<=> y = 53

> x = 80 - 53 = 27

the number of single room is 27 and the number of double room  is 53

An animal shelter houses ferrets, cats, and dogs. There are 108 animals at the shelter. Of the
Korvikt [17]

Number of dogs in the shelter are 12

<u>Step-by-step explanation:</u>

Step 1:

Given that total animals = 108 and number of ferrets = 1/3 of 108. Find number of ferrets in the shelter.

Number of ferrets = 1/3 of 108 = 1/3 × 108 = 36

Step 2:

Given that of the remaining animals, number of cats = 5/6. Find the remaining animals and the number of cats.

Remaining number of animals = 108 - 36 = 72

Number of cats = 5/6 of 72 = 5/6 × 72 = 60

Step 3:

Find number of dogs in the shelter.

Number of dogs = 108 - (36 + 60) = 108 - 96 = 12

Find the next 2 terms in the Geometric sequence 20,30,45 ...
DochEvi [55]

Answers:

The next two terms are 67.5 and 101.25 in that order.

===========================================

Explanation:

Divide the second term over the first to get 30/20 = 1.5

Divide the third term over the second term to get 45/30 = 1.5

The common ratio is 1.5, which means we multiply 1.5 by each term to get the next term

-------

fourth term = 1.5*(third term) = 1.5*45 = 67.5

fifth term = 1.5*(fourth term) = 1.5*67.5 = 101.25

-------

As a shortcut you can plug n = 4 and n = 5 into the function t(n) = 20*(1.5)^(n-1) to get the fourth and fifth terms respectively.

Since there are 120 payment and the total interest paid was $ 14,644.95. so the average monthly interest can be calculated by:

Average monthly interest = $ 14,644.95 / 120

Average monthly interest = $ 122.04

 

% total interest = ($ 14,644.95) / $ 39,644.95 x 100

% total interest =36.94 %
