Best ResponseYou've already chosen the best response.0Jones family: 2*adults + 3*kids = $47 total 2*a + 3*k = 47 2a + 3k = 47

Best ResponseYou've already chosen the best response.0all three of those equations represent the same thing

Best ResponseYou've already chosen the best response.0can you set up an equation for the Smith family now?

Best ResponseYou've already chosen the best response.03a+5k=74.75 whats next?? @bi

Best ResponseYou've already chosen the best response.0perfect now you have two equations and two unknowns, can you solve this system for a and k? 2a + 3k = 47 3a + 5k = 74.75

Best ResponseYou've already chosen the best response.0hmm ok, the easiest way would be either elimination or substitution, which do you prefer?

Best ResponseYou've already chosen the best response.0what is the last sentence supposed to say? "How much does the Ramirez family have to pay with adults and four kids"

anonymous

Best ResponseYou've already chosen the best response.0its missing the number of adults

Best ResponseYou've already chosen the best response.0with four adults and four kids

Best ResponseYou've already chosen the best response.0ok solve one of those 2 equations for either a or k, you choose

Best ResponseYou've already chosen the best response.02a + 3k = 47, lets solve for a, so first subtract 3k from both sides

anonymous

Best ResponseYou've already chosen the best response.02a = 47  3k, now divide both sides by 2

Best ResponseYou've already chosen the best response.0no, a = (47  3k) / 2

Best ResponseYou've already chosen the best response.0and what will be the answer

Best ResponseYou've already chosen the best response.0we are working on it

Best ResponseYou've already chosen the best response.0do you understand how we got a = (47  3k) / 2

anonymous

Best ResponseYou've already chosen the best response.0ok so now you know the value of a, we cannot plug it back into the same equation because we will not get any new information, so lets plug it into the other equation

anonymous

Best ResponseYou've already chosen the best response.0can you please plug what we found for a, into the other equation?

anonymous

Best ResponseYou've already chosen the best response.0thats true but you need to plug what we found for a into that equation

anonymous

Best ResponseYou've already chosen the best response.0so that we can solve for k

anonymous

Best ResponseYou've already chosen the best response.0can u plug it in.. I'm kinda lost

anonymous

Best ResponseYou've already chosen the best response.0ok lets start again, because me doing it for you wont help anyone

Best ResponseYou've already chosen the best response.0we have these two equations that we came up with 2a + 3k = 47 3a + 5k = 74.75

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0we looked at the first equation and solved for a 2a + 3k = 47 2a = 47  3k a = (47  3k) / 2

anonymous

Best ResponseYou've already chosen the best response.0now we plug that value for a, into the second equation 3a + 5k = 74.75 3(plug in here) + 5k = 74.75

Best ResponseYou've already chosen the best response.0thats very close but you left out the divide by 2, i will put it in for you 3((473k)/2)+5k=74.75

anonymous

Best ResponseYou've already chosen the best response.0$$3*\frac{473k}{2} + 5k = 74.75$$

anonymous

Best ResponseYou've already chosen the best response.0now you need to solve that for k

anonymous

Best ResponseYou've already chosen the best response.0by the way elimination method would have been much easier, but thats ok this is good practice

anonymous

Best ResponseYou've already chosen the best response.0so solve that for k and what do you get for k?

anonymous

Best ResponseYou've already chosen the best response.0im not sure how you do it

anonymous

Best ResponseYou've already chosen the best response.0maybe it will help to write (47  3k) / 2 as separate fractions, can you do that?
