A barista mixes 12 lb of his secret-formula coffee beans with 15 lb of another bean that sells for $18 per lb. The resulting mix costs 20$ per lb. How much do the baristas secret formula beans cost per pound

The answer is the secret beans cost $22.5 per pound.

Step-by Step: Step 1: make an equation. 12 lbs is the secret formula, and the cost in unknown lets put that as x. So 12 lbs +15 lbs of $18 mix which is the coffee beans =$20 per lbs. So the total amount is is 27 lbs. Now lets right the equation. 12x+15(18)=20(27) solve for x normally 12x+270=540        12x=270      x=22.5 SO the final answer is $22.5 I hope this helped.

your answer would be 10x - 1
