Arabica coffee costs 28$ per pound and Robusta coffee costs8.75 per pound how many pounds of Arabica coffee should you mix with 5 pounds of robusta coffee to make a coffee blen that costs 12$ per pound?

Amount of Arabica coffee mixing = 1.016 pounds

Step-by-step explanation:

Cost of Arabica coffee = 28$ per pound

Cost of Robusta coffee = 8.75$ per pound

Amount of Robusta coffee mixing = 5 pounds

Cost for 5 pounds of Robusta coffee = 5 x 8.75 = 43.75 $

Let m be the Amount of Arabica coffee mixing, we have price of mix = 12$ per pound

That is

43.75 + m x 28 = (m + 5) x 12

43.75 + 16 m = 60

16 m = 16.25

m = 1.016 pounds

Amount of Arabica coffee mixing = 1.016 pounds

you cant. sorry but if you mulitply 5 times 8.75 than you would get 43.75. make sure you copied the question correctly
