can anyone help me set up the equation of: Cashews are priced at $5.75 per pound. Peanuts are priced at $3.25 per pound. Mixed together to total 80 pounds for $4.00 per pound. How many pounds of each do I need?

Best ResponseYou've already chosen the best response.0x+y=80 3.25x+5.75y=4.00 Pretty sure that is right just use the elimination or substitution methode to figure it out

Best ResponseYou've already chosen the best response.0my class is not to substitution or elimination. i was thinking: 3.25x+5.75(x80)=320?

Best ResponseYou've already chosen the best response.0i don't know how you would solve that if you are not using one of those methodes. to me it looks like it should be a set of equations in multi varible form. let me think of this for a sec.

Best ResponseYou've already chosen the best response.0its helpful to use variables that represent the actual stuff :) c for Cashew and p for peanuts helps you to keep track of them better ;) other than that you did a great job with it

Best ResponseYou've already chosen the best response.0c+p=80 p(3.25)+c(5.75)=(80)4.00

Best ResponseYou've already chosen the best response.0solve for one variable in the first equation: c = 80p and substitute it into the second.... p(3.25)+(80p)(5.75)=(80)4.00 do the math, and solve for p..

Best ResponseYou've already chosen the best response.0once you know a solid value for "p" use it in the c = 80p to find c.
