Question

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 38 more deluxe staterooms than the Pacific Paradise. The Mediterranean Paradise has 10 fewer deluxe staterooms than 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 598

Answer 1

P + C + M = 598

C = 38 + P

M = P - 10

P + 38+P + P-10 = 598

3P = 598 -28 = 570

P = 570/3 = 190 Pacific Paradise

C = 228 Caribbean Paradise

M = 180 Mediterranean Paradise

180+190+228= 598
