Problem:

Художнику было необходимо сделать 68 рисунков к мультфильму. После того, как он сделал 20 рисунков в понедельник и несколько рисунков во вторник, ему осталось сделать 25 рисунков. Сколько рисунков художник сделал во вторник? Реши задачу двумя способами!

Solution 1:

To solve this problem, we can use the information given and subtract the number of drawings made on Monday from the total number of drawings that need to be done. Then, we subtract the remaining number of drawings from the total number of drawings that need to be done to find the number of drawings made on Tuesday.

1. Number of drawings made on Monday: 20 2. Remaining number of drawings: 25 3. Total number of drawings: 68

To find the number of drawings made on Tuesday, we can subtract the number of drawings made on Monday from the total number of drawings and then subtract the remaining number of drawings:

Total number of drawings - Number of drawings made on Monday - Remaining number of drawings = Number of drawings made on Tuesday

68 - 20 - 25 = 23

Therefore, the artist made 23 drawings on Tuesday.

Solution 2:

Another way to solve this problem is by using the concept of algebraic equations.

Let's assume the number of drawings made on Tuesday is represented by the variable 'x'.

1. Number of drawings made on Monday: 20 2. Remaining number of drawings: 25 3. Total number of drawings: 68

We can set up the following equation:

Number of drawings made on Monday + Number of drawings made on Tuesday + Remaining number of drawings = Total number of drawings

20 + x + 25 = 68

Simplifying the equation:

x + 45 = 68

Subtracting 45 from both sides of the equation:

x = 68 - 45

x = 23

Therefore, the artist made 23 drawings on Tuesday.

Both methods yield the same result, confirming that the artist made 23 drawings on Tuesday.
