Problema Solution
A new cruise ship has just launched 3 new ships the pacific the caribou and the Mediterranean. The caribou has 22 more deluxe staterooms than the pacific. The Mediterranean has 31 fewer deluxe staterooms than twice the number on the pacific . Find the number of deluxe staterooms for each ship if the total staterooms for all 3 ships is 719
Answer provided by our tutors
Let the number of deluxe staterooms in pacific the caribou and the Mediterranea be x, y, z.
so here y = x + 22
and z = 2x - 31
and x+ y + z = 719
so
=> x + x + 22 + 2x - 31 = 719
=> 4x - 9 = 719
=> 4x = 719 + 9
=> x = 728/4 = 182
y = 182 + 22 = 204
z = 2*182 - 31 = 364 - 31= 333
so the number of deluxe staterooms in pacific the caribou and the Mediterranea are 182, 204, 333.ANS
