which of the following equations models the mixing of walnuts at $2.50/lb and cashews at $2.25/lb with peanuts at $1.25/lb to make 10 lb of a mixture costing $2.00/lb?

Answer 1

Price. Amount. Total

Walnuts. 2.50. X. 2.5x

Cashews. 2.25. Y. 2.25y

Peanuts. 1.25. 10-x-y. 1.25(10-x-y)

Mixture. 2.00. 10. 2(10)=20

Equation:

2.5x+2.25y+1.25(10-x-y)=20

Simplify

Answer 2

Well, you don't give any choices but it would look something like...

2.5w + 2.25c + 1.25p = 2(w + c + p)
