The answer would c & d in this case
C = caribbean, p = pacific, m = mediterranean
c = p + 29
m = 2p - 30
c + m + p = 719
(p + 29) + (2p - 30) + p = 719
4p - 1 = 719
4p = 719 + 1
4p = 720
p = 720/4
p = 180 <=== pacific paradise deluxe staterooms
c = p + 29
c = 180 + 29
c = 209 <=== caribbean paradise deluxe staterooms
m = 2p - 30
m = 2(180) - 30
m = 360 - 30
m = 330 <=== mediterranean paradise deluxe staterooms
The answer to the first one = 164
The answer to your second one = 1230
Malachy- $9
Gavin- $3
Gavyn- $6
Solution;
Add up all the numbers in the ratios. So 3+1+2 is 6. Now do the money ($18) divided by the tattled up ratio (6). 18 divided by 6 is $3 which is now equal to 1. Now for malachy you do his ratio (3) times our number equal to one of those ratios (3). 3 times by 3 is $9. Same for others. 1 times 3 is 3. 2 times 3 is 6.
