for his long distance phone service, lamar pays a $3 monthly fee plus 11 cents per minute. last month, lamar's long distance bill was $20.82 . for how many minutes was lamar billed
Answers
Cost per minute = 11 cents = 0.11
Phone Bill = Monthly fee + 0.11* x
Substituting from the question
20.82 = 3 + 0.11x
3 + 0.11x = 20.82
0.11x = 20.82 - 3
0.11x = 17.82
x = 17.82/0.11
x = 162
Lamar was billed for 162 minutes.

So in 4 years, there are 365 × 4 = 1460 days.
However, every 4 years, there is also a "leap day." (an additional day in February of years divisible by 4 to balance the calendar)
After adding this day, we would have 1461 days in 4 consecutive years.
*Note: There are exceptions to when leap years happen, so on some 4 year periods there is no leap year. In that case, there could be just 1460.
In four consecutive years, there are 1461 days.
How did we get the value?
To determine the total number of days in four consecutive years, we need to consider whether those years are regular years or leap years.
A regular year has 365 days, while a leap year has 366 days. Leap years occur every four years, with some exceptions. The exceptions are years divisible by 100 but not divisible by 400, which are not leap years.
To calculate the number of days in fourconsecutive years, we first determine if any of the years in that span are leap years. If one or more of the years are leap years, we add an extra day for each leap year.
Let's consider the four-year period starting from the current year, 2023:
Year 2023: Regular year (365 days)
Year 2024: Leap year (366 days)
Year 2025: Regular year (365 days)
Year 2026: Regular year (365 days)
To calculate the total number of days in this four-year span, we add up the days for each year:
365 + 366 + 365 + 365 = 1461
Therefore, in four consecutive years, there are 1461 days.

?how many gallons......................................60 seconds(1min)
to find out you do 9*60=540 gallons per minute
xgals/minute
1 minute=60 seconds
xgals/60 seconds=9gals/1 second
x/60=9/1
solve for x
x/60=9/1
x/60=9
multily both sides by 60 to clear fraciton
x times 60/60=9 times 60
x times 60/60=x times 1=x
x=540
the answer is 540 gallons per minute
