Answer:- $0.75 per kg and $0.50 per kg

let the price of sugar and rice be X and y respectively.

now ,

according to question,

3x + 2y = 3.25 $_____eq.(I)

2x + 2y = 2.50 $______eq.(II)

subtracting eq(II) from eq(I) , we get

2y will be cancelled and remains

X = 0.75 $

therefore , the price of sugar = 0.75 $ per kg.

and

substituting X = 0.75 in eq.(II) , we get

2*0.75 + 2* Y = 2.50

or, 2Y = 2.50- 1.50

or,. Y = 1/2= 0.5

hence , the price of rice is 0.5 $ per gram.

Albertson's found that the demand for Coke products varies inversely as the price of the product. When the price of a Coke produ
romanna [79]

Answer:

859

Step-by-step explanation:

The demand for Coke products varies inversely as the price of Cole products.

Mathematically:

D α 1/p

Where D = demand, p = price of coke product

D = k/p

Where k = constant of proportionality.

Let us find k.

k = D * p

When Demand, D, is 1250, price, p, is $2.75:

=> k = 1250 * 2.75

k = $3437.5

Now, when price, p, is $4, the demand will be:

D = 3437.5/4

D = 859.375 = 859 (rounding to whole number)

The demand for the product is 859 when the price is $4.
