Могут ли 10 игрушек ценой в 3,5 или 7 рублей стоить в сумме 53 рубля? почему?

Answer 1

Can 10 toys priced at 3.5 or 7 rubles each cost a total of 53 rubles? Why?

To determine if 10 toys priced at 3.5 or 7 rubles each can cost a total of 53 rubles, we need to consider the possible combinations of toy prices.

Let's analyze the different scenarios:

1. If all 10 toys are priced at 3.5 rubles each: - The total cost would be 10 * 3.5 = 35 rubles.

2. If all 10 toys are priced at 7 rubles each: - The total cost would be 10 * 7 = 70 rubles.

3. If there is a combination of toys priced at 3.5 and 7 rubles each: - Let's assume x toys are priced at 3.5 rubles and y toys are priced at 7 rubles. - The total cost would be (x * 3.5) + (y * 7) = 53 rubles.

To find the possible values of x and y, we can use algebraic equations. However, based on the given information, it is not possible to determine the exact values of x and y without additional constraints or equations.

Therefore, it is not possible to definitively say whether 10 toys priced at 3.5 or 7 rubles each can cost a total of 53 rubles without more information.
