Question

Летом Вася 12 часов в неделю работает помощником слесаря. За каждый час работы он получает 3 рубль. Сможет ли он накопить денег на покупку музыкального центра за 199 рубль, если проработает 5 недель?

Answer 1

12 часов в неделю  следовательно в неделю он получает 36 рублей (12*3=36)
за 5 недель он получит 180 рублей(5*36=180). следовательно он не сможет накопить.

Answer 2

Calculation of Vasya's earnings

To determine if Vasya can save enough money to buy a music center, we need to calculate his earnings over the course of 5 weeks.

Vasya works as an assistant to a locksmith for 12 hours per week, and he earns 3 rubles per hour of work. Therefore, his weekly earnings can be calculated as follows:

Weekly earnings = Number of hours worked per week * Earnings per hour

Substituting the given values:

Weekly earnings = 12 hours/week * 3 rubles/hour

Calculating the weekly earnings:

Weekly earnings = 36 rubles/week

Total earnings over 5 weeks

To calculate Vasya's total earnings over 5 weeks, we multiply his weekly earnings by the number of weeks:

Total earnings = Weekly earnings * Number of weeks

Substituting the given values:

Total earnings = 36 rubles/week * 5 weeks

Calculating the total earnings:

Total earnings = 180 rubles

Affordability of the music center

The cost of the music center is 199 rubles. Since Vasya has earned 180 rubles, he does not have enough money to afford the music center. He is 19 rubles short.

Therefore, based on the given information, Vasya will not be able to save enough money to buy the music center after working for 5 weeks.

Please note that the information provided is based on the given scenario and calculations.
