A new cruise ship line has just launched 3 new ships: the Pacific, the Caribbean, and the Mediterranean. The Caribbean has 15 more deluxe staterooms than the Pacific. The Mediterranean has 26 fewer deluxe staterooms than four times the number of deluxe staterooms on the Pacific. Find the number of deluxe staterooms for each of the ships if the total number of deluxe staterooms for the three ships is 805.

Let P = the Pacific
P + P + 15 + 4P  26 = 805
6P  11 = 805
6P = 816
P = 136
