## MauriceLong 3 years ago Can someone help me please... Thanks A new cruise ship line has just launched 3 new ships; the Pacific Paradise, the Carribean Paradise and the Mediterranean Paradise. The Carribean Paradise has 28 more deluxe staterooms than the Pacific Paradise. The Mediterranean Paradise has 29 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 881. The Pacific Paradise has______deluxe staterooms The Caribbean Paradise has____deluxe

Step 1 Read the problem carefully. Decide what unknown numbers are asked for and what facts are known.

2. MauriceLong

Im still confuse with this problem.

Decide what unknown numbers are asked for. Find the number of deluxe staterooms for each of the ships

6. MauriceLong

28,29,881

7. skullpatrol

How?

8. MauriceLong

I still dont get this

9. skullpatrol

Let P = the number of rooms on the Pacific, since The Carribean Paradise has 28 more deluxe staterooms than the Pacific Paradise. Then C = 28 + P.

10. MauriceLong

ok

11. skullpatrol

The Mediterranean Paradise has 29 fewer deluxe staterooms than four times the number of deluxe staterooms on the Pacific Paradise. M =4P - 29

12. MauriceLong

k

13. skullpatrol

P, C, M P = the number of rooms on the Pacific C = 28 + P M =4P - 29

14. MauriceLong

ok

15. skullpatrol

Step 3 Reread the problem and write an equation that represents relations among the numbers in the problem.

16. skullpatrol

P + C + M = 881 if the total number of deluxe staterooms for the three ships is 881.

17. MauriceLong

3+28+4p-29=881

18. skullpatrol

Substitute into P + C + M = 881 the three: P = the number of rooms on the Pacific C = 28 + P M =4P - 29

19. skullpatrol

P + C + M = 881 P +(28 + P) + (4P -29) = 881

20. MauriceLong

so, p+(28+p)+(4p-29)=881 = 147

21. MauriceLong

sorry i got confuse with the problem. didnt mean too put 147

22. skullpatrol

Step 4 Solve the equation and find the unknowns asked for.

23. MauriceLong

ok. how do i find the unknow answer for The Pacific Paradise has______deluxe staterooms The Caribbean Paradise has____deluxe The mediterranean Paradise has___deluxe staterooms

24. skullpatrol

Solve the equation: p+(28+p)+(4p-29)=881 for p= the number of rooms on the Pacific

25. MauriceLong

the number of rooms on the ship is 881

26. skullpatrol

Solve the equation: p+(28+p)+(4p-29)=881 for p

27. MauriceLong

p=147

28. skullpatrol

Very good :-)

29. MauriceLong

What are the answers for all three. p= 147 The Pacific Paradise has______deluxe staterooms The Caribbean Paradise has____deluxe The mediterranean Paradise has___deluxe staterooms

30. skullpatrol

So now you know how many rooms are on the Pacific= 147rooms. To find the others substitute this value into: C = 28 + P M =4P - 29

31. MauriceLong

c= 28+P=147

32. MauriceLong

im still confuse a little.

33. MauriceLong

34. skullpatrol

Sub p=147 into c= 28+p

35. skullpatrol

|dw:1353571177390:dw|

36. skullpatrol

To find the number of rooms on the Mediterranean Paradise sub P = 147 into: M =4P - 29

37. skullpatrol

Step 5 Check your results with the words of the problem. Give the answer.
