For his coffee shop, abdul wants to make a mocha-java blend that will sell for $18/kg. the mocha coffee beans sell for $20/kg, and the java coffee beans sell for $15/kg. how many kilograms of each kind of coffee bean should he use to make 50 kg of the mocha-java blend?

Step-by-step explanation:

let

x = kg of mocha beans

y = kg of java beans

so

(1)   x + y = 50

(2)   20x + 15y = 18(50)

solve by substitution (or whatever method you prefer):

(x, y) = (30, 20)

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
