Question

Васильевы купили принтер за 3600 рублей. Один картридж (часть принтера, заправленная чернилами для печати) без заправки может отпечатать 2000 страниц.Всем членам семьи Васильевых за месяц обычно надо напечатать не более 150 страниц. Хватит ли этого картриджа на 1,5 года?

Answer 1

150 х 18 = 2700 (стр.) – напечатают Васильевы за 1,5 года
Ответ: Данного картриджа не хватит семье Васильевых на 1,5 года.

Answer 2

Calculation of Cartridge Usage

To determine if the cartridge will last for 1.5 years, we need to calculate the number of pages the Vasilev family will print in that time period.

The Vasilev family typically needs to print no more than 150 pages per month. Therefore, we can calculate the number of pages they will print in 1.5 years as follows:

Number of pages printed per month: 150 Number of months in 1.5 years: 1.5 * 12 = 18

Total number of pages printed in 1.5 years: 150 * 18 = 2700 pages

Cartridge Capacity

The cartridge can print 2000 pages when it is fully filled with ink. However, it is mentioned that the cartridge is not yet filled with ink. Therefore, we need to consider the cartridge's current ink level.

Unfortunately, the information provided does not specify the current ink level in the cartridge. Without this information, it is not possible to accurately determine if the cartridge will last for 1.5 years.

However, if we assume that the cartridge is completely empty, we can calculate the number of cartridges the Vasilev family will need in 1.5 years:

Number of cartridges needed: 2700 pages / 2000 pages per cartridge = 1.35 cartridges

Since we cannot use a fraction of a cartridge, the Vasilev family would need to purchase at least 2 cartridges to cover their printing needs for 1.5 years.

Conclusion

Based on the information provided, it is not possible to determine if a single cartridge will last for 1.5 years for the Vasilev family. The calculation depends on the current ink level in the cartridge, which is not specified. However, if we assume the cartridge is completely empty, the family would need to purchase at least 2 cartridges to cover their printing needs for 1.5 years.
