Answer 3

To find the cost of 300 grams, you can set up a proportion based on the given information:

450 grams = 130 rubles 300 grams = ?

The proportion can be set up as follows:

(450 grams) / (130 rubles) = (300 grams) / (x rubles)

Now, cross-multiply and solve for x:

450x = 130 * 300 450x = 39000

Now, divide both sides by 450 to find the value of x:

x = 39000 / 450 x = 86.67

Therefore, the cost of 300 grams is approximately 86.67 rubles. Since it's common to deal with currency in whole numbers, you might round it to the nearest ruble, so the answer is around 87 rubles.
