Best ResponseYou've already chosen the best response.0Try breaking the paragraph up. Each sentence corresponds to an equation. \[ \text{Let }r_1\text{ be the number of rooms in boat A, etc.} Then use the equations to solve for each r

Best ResponseYou've already chosen the best response.0So for the first sentence: "Boat B has 15 more rooms than boat A." What would the equation representing this statement look like?

Best ResponseYou've already chosen the best response.0Very nearly. From your equation which boat has the greater number of rooms? And does that coincide with the information presented in the statement?

Best ResponseYou've already chosen the best response.0from what i under stand: A=? B=15+A C=2A39

Best ResponseYou've already chosen the best response.0Yes, that's it exactly. Now we know one more thing which is that there is a total of 388 rooms. So write the equation for that statement.

Best ResponseYou've already chosen the best response.0Right. So now take what you know about C and B and replace those variables with expressions that have A instead.

Best ResponseYou've already chosen the best response.0Yep. Then solve for A.

Best ResponseYou've already chosen the best response.0Once you know A, you can go back to the equations for B and C to find what those are.

Best ResponseYou've already chosen the best response.0Certainly. Just remember that each sentence is telling you something. Typically it translates directly into an equation, and by using all your equations you can do substitution to solve for one of your variables. Then once you have one you can find the others.
