Question

для кабінету фізики купили 10 однакових комп'ютерів а для кабінету інформатики 15 таких самих комп'ютерів вартість яких на 45000 грн більше від вартості комп'ютерів для кабінету фізики. Яка ціна одного компьютера?​

Answer 1

Пошаговое объяснение:

15-10=5 (к)-різниця

45000:5= 9000(грн) -вартість 1 комп'ютера

в:вартість 1 комп'ютера-9000 грн

думаю, так

Answer 2

Calculation of the Price of One Computer

To calculate the price of one computer, we need to consider the information provided.

It is mentioned that 10 identical computers were purchased for the physics classroom, while 15 identical computers were purchased for the computer science classroom. The cost of the computers for the computer science classroom is 45,000 UAH more than the cost of the computers for the physics classroom.

Let's assume the price of one computer for the physics classroom is X UAH.

According to the given information, the cost of 10 computers for the physics classroom would be 10X UAH.

Similarly, the cost of 15 computers for the computer science classroom would be 15(X + 45,000) UAH.

Since the cost of the computers for the computer science classroom is 45,000 UAH more than the cost of the computers for the physics classroom, we can set up the following equation:

15(X + 45,000) = 10X

Now, let's solve this equation to find the value of X, which represents the price of one computer for the physics classroom.

15X + 675,000 = 10X

5X = 675,000

X = 675,000 / 5

X = 135,000

Therefore, the price of one computer for the physics classroom is 135,000 UAH.
