Question 1113058
A new cruise ship line has just launched 3 new​ ships: the Pacific​ Paradise, the Caribbean​ Paradise, and the Mediterranean Paradise. 
The Caribbean Paradise has 30 more deluxe state rooms than the Pacific Paradise. The Mediterranean Paradise has 35 fewer deluxe staterooms than four times the number of deluxe staterooms on the Pacific Paradise. 
Find the number of deluxe staterooms for each of the ships if the total number of deluxe staterooms for the three ships is 1165.
-----
Equations:
P + C + M = 1165
C = P + 30
M = 4P-35
--------------------
Substitute and solve for "P":
P + P+30 + 4P-35 = 1165
6P = 1170
P = 195 (# on PP)
C = 195+30 = 225 (# on CP)
M = 4P-35 = 745 (# on MP)
