Final answer:
To find the total number of minutes Brad volunteers in one year, we need to calculate the number of minutes he volunteers each week and then multiply it by the number of weeks in a year. On Saturdays, Brad volunteers for 40 minutes, and on Sundays, he volunteers for 30 minutes. In one week, he volunteers for a total of 70 minutes. Therefore, he volunteers for a total of 3500 minutes in one year.
Step-by-step explanation:
To find the total number of minutes Brad volunteers in one year, we need to calculate the number of minutes he volunteers each week and then multiply it by the number of weeks in a year.
On Saturdays, Brad volunteers for 40 minutes, and on Sundays, he volunteers for 30 minutes. In one week, he volunteers for a total of 70 minutes (40 + 30).
Since Brad takes 2 weeks off for vacation each year, we subtract those weeks from the total number of weeks in a year, which is 52. Therefore, he volunteers for 50 weeks in a year.
Multiplying the number of minutes Brad volunteers in a week (70) by the number of weeks in a year (50), gives us the total number of minutes, which is 3500 minutes.
