Question

Купили несколько тетрадей в линейку по 16 рублей и в клетку по 17 затратив на всю покупку 182 р . Сколько куплено тетрадей каждого вида

Answer 1

Calculation of the Number of Notebooks Purchased

To calculate the number of notebooks purchased, we need to set up a system of equations based on the given information.

Let's assume that the number of notebooks purchased in a lined format is represented by x, and the number of notebooks purchased in a grid format is represented by y.

According to the given information, the cost of each lined notebook is 16 rubles, and the cost of each grid notebook is 17 rubles. The total cost of the purchase is 182 rubles.

We can set up the following equations:

1. The cost equation: 16x + 17y = 182 2. The quantity equation: x + y = ?

To solve this system of equations, we can use substitution or elimination.

Let's use the elimination method to solve the equations:

Multiplying the second equation by 16, we get:

16x + 16y = 16 * ?

Subtracting this equation from the first equation, we eliminate the variable x:

16x + 17y - (16x + 16y) = 182 - (16 * ?)

Simplifying the equation, we have:

y = 182 - (16 * ?)

Now, we can substitute this value of y into the second equation to solve for x:

x + (182 - (16 * ?)) = ?

Simplifying the equation, we have:

x = ? - (182 - (16 * ?))

To find the values of x and y, we need to know the value of "?" in the second equation. Unfortunately, the given information does not provide this value, so we cannot determine the exact number of notebooks purchased in each format.

If you can provide the missing value, I would be happy to help you calculate the number of notebooks purchased in each format.
