Answer 2

Mathematical Model 1: За конфеты заплатили а руб, а за печенье б руб, а-б=17

This mathematical model represents a situation where the cost of candies and cookies is given in rubles. The equation a - b = 17 is used to express the relationship between the two prices.

To solve this equation, we need to find the values of a and b that satisfy the equation. Since we only have one equation with two variables, we cannot determine the exact values of a and b. However, we can express one variable in terms of the other.

Let's solve the equation for a in terms of b: a - b = 17 a = b + 17

Now we have an expression for a in terms of b. This means that for any given value of b, we can calculate the corresponding value of a by adding 17 to b.

For example, if we assume b = 5, then a = 5 + 17 = 22. This means that the cost of candies is 22 rubles and the cost of cookies is 5 rubles.

It's important to note that without additional information or constraints, we cannot determine the specific values of a and b. The equation a - b = 17 represents a relationship between the two prices, but it does not provide enough information to uniquely determine their values.
