: I recently asked this question but forgot to put all the info(sorry).
33. Crystal owns and operates a gourmet tea and coffee shop. Monica, who is one of Crystal's best customer, wants to buy two kinds of beans: Arabian Mocha and Colombian Decaf. If she wants twice as much Mocha as Decaf, how much of each can she buy for a total of $87.50?
Colombian Decaf = 8.00/lb
Arabian Mocha = 8.50/lb
Thank you. This question is from textbook beginning algebra

Answer by rfer(16322) (Show Source): You can put this solution on YOUR website!
let decaf = x
let mocha = 2x
8.50(2x)+8.00x=87.50
17x+8x=87.50
25x=87.50
x=3.5 lb
2x=7 lb
decaf=8*3.5=$28
mocha=8.5*2*3.5=$59.50
