How many pounds of arabica coffee should you mix with 5 pounds of robusta coffee to make a coffee blend that costs $12.00 per pound?

Answers

Approximately 1.02lb of arabica coffee should be mixed with 5lb of robusta coffee to make a coffee blend that costs $12.00 per pound.

Let x lb be the amount of arabica coffee that should be mixed with 5lb robusta.

Thus, total cost of Arabica coffee= $28*x

and since cost of robusta coffee per pound is $8.75, thus cost for 5lb= $8.75*5= $43.75

also, total amount of coffee for coffee blend = x+5

thus, total cost for coffee blend= $12(x+5)

Since, Arabica+ Robusta= Mixture

⇒ $28*x + $43.75 = $12(x+5)

⇒ $28*x + $43.75 = $12x + $60

⇒ $28*x – $12x = $60 – $43.75

⇒$16x = $ 16.25

⇒ x = 1.0156 ≈ 1.02lb

hence, 1.02 pounds of arabica coffee should you mix with 5 pounds of robusta coffee to make a coffee blend that costs $12.00 per pound
