A candy store currently sells almonds for $8.50 per kilogram and peanuts for $4.50 per kilogram. It wants to create 20 kilograms of mixed nuts that will equivalently sell for $5.30 per kilogram. How many kilograms of almonds should they use?
almonds rate per kg is $8.50 , peanuts price per kg is $4.50 and avg price is $5.30
so subtract avg value from the given prices we will get the ratio of almonds to peanuts
so the ratio of almonds to peanuts is
3.2 : 0.8
but by the method the ratio gets flipped so the new ratio of almonds to peanuts is
0.8 : 3.2
4 kg is the right answer
