Question

Выпуская в день одинаковое количество соковыживалок, завод изготовил 31280 соковыжималок за 20 дней. сколько соковыжималок выпустил завод за месяц (30 дней), если ежедневно они будут выпускать на 16 соковыжималок больше? Номер 5 тоже Пж

Answer 1

1) 31280:20=1564 (шт)- за 1 день
2)1564+16=1580 (шт)- если на 16 больше
3) 1580×30=47400 (шт)- за месяц

Answer 2

To solve this problem, we can set up an equation based on the given information. Let's denote the number of juice extractors produced per day as "x". According to the problem, the factory produced 31280 juice extractors in 20 days. Therefore, we can write the equation:

20x = 31280

To find the number of juice extractors produced in a month (30 days), we need to consider that they will be producing 16 more juice extractors per day. So, the equation becomes:

30(x + 16) = ?

Let's solve these equations step by step.

Solving the first equation:

20x = 31280

Dividing both sides of the equation by 20: x = 31280 / 20 x = 1564

Therefore, the factory produced 1564 juice extractors per day.

Solving the second equation:

30(x + 16) = ?

Substituting the value of x from the first equation: 30(1564 + 16) = ?

Calculating the expression inside the parentheses: 30(1580) = ?

Multiplying: 47400 = ?

Therefore, the factory will produce 47400 juice extractors in a month (30 days) if they produce 16 more juice extractors per day.
