Телевизор стоит : 2460 * 4 = 9840 руб

Всё стоит : 2460 + 9840 + 6180 = 18480 руб .
Выделенных денег хватит на покупку

Answer 3

Calculation of Total Cost

To determine if the allocated budget of 20,000 rubles is sufficient to purchase a television, an audio system, and a DVD player, we need to calculate the total cost of these items.

Let's break down the given information: - The cost of the audio system (audimagnitola) is 2,460 rubles, which is 4 times less than the cost of the television. - The cost of the DVD player (dividi) is 3,720 rubles less than the cost of the television.

Based on this information, we can calculate the cost of the television as follows:

Cost of the audio system = 2,460 rubles Cost of the DVD player = Cost of the television - 3,720 rubles

Since the cost of the audio system is 4 times less than the cost of the television, we can express it as:

Cost of the audio system = (1/4) * Cost of the television

By substituting the value of the audio system cost, we can solve for the cost of the television:

2,460 rubles = (1/4) * Cost of the television

Simplifying the equation, we find:

Cost of the television = 2,460 rubles * 4 = 9,840 rubles

Now, we can calculate the total cost of all three items:

Total cost = Cost of the television + Cost of the audio system + Cost of the DVD player

Total cost = 9,840 rubles + 2,460 rubles + (9,840 rubles - 3,720 rubles) = 9,840 rubles + 2,460 rubles + 6,120 rubles = 18,420 rubles

Conclusion

The total cost of purchasing a television, audio system, and DVD player is 18,420 rubles. Since the allocated budget is 20,000 rubles, there is enough money to cover the cost of these items.
