A new cruise ship line has just launched 3 new​ ships: the Pacific​ Paradise, the Caribbean​ Paradise, and the Mediterranean Par
Elenna [48]

Answer:

Pacific Paradise deluxe state rooms=116

Caribbean Paradise deluxe state rooms = 127

Mediterranean Paradise deluxe state rooms = 333

Step-by-step explanation:

Hi, the numbers are doubled, the correct values are:  

<em>Caribbean Paradise has 11 more deluxe staterooms than the Pacific Paradise. </em>

<em>Mediterranean Paradise has 15 fewer deluxe staterooms than three times the number of deluxe staterooms on the Pacific Paradise.  </em>

<em>Total number of deluxe staterooms for the three ships is 576. </em>

So, to solve we have to write 3 equations.

C =11 +P

M = P3-15

C+M+P =576

Where:

  • <em>C: number of Caribbean Paradise deluxe state rooms </em>
  • <em>M: number of Mediterranean Paradise deluxe state rooms </em>
  • <em>P: number of Pacific Paradise deluxe state rooms </em>

Replacing values in the total ships equation:

(11 +P) + (P3-15)+P =576

Solving for P:

11 -15 +P+P+3P =576

-4 +5P =576

5P =576+4

5P =580

P = 580/5

P=116

Replacing P in each ship's equation

C = 11 +P= 11 +(116) =127

M =3P -15 = 3 (116)-15 = 333
