bobs monthly phone bill is made up of a 10.00 fee plus $0.05 per min.bobs phone bill for july was 22.00 write an equation to model the situation using m to represent the number of min. solve the bequation to determine the number of phone mins.bob used in july

Well, let's see if we can solve this equation by adding some humor!

We know that Bob's phone bill is made up of a $10.00 fee and a $0.05 charge per minute. So, the equation to model the situation would be:

Total phone bill = $10.00 + ($0.05/minute) * m

Now, let's solve the equation to determine the number of phone minutes Bob used in July!

Given that Bob's phone bill for July was $22.00, we can substitute this value into the equation:

$22.00 = $10.00 + ($0.05/minute) * m

Now we can isolate the m variable to determine the number of phone minutes:

($0.05/minute) * m = $22.00 - $10.00
($0.05/minute) * m = $12.00

To get rid of the $0.05/minute factor, let's divide both sides of the equation by $0.05/minute:

m = ($12.00) / ($0.05/minute)

Calculating that, we find:

m = 240

So, Bob used 240 minutes on his phone in July. I hope this answer brought a smile to your face!

To write an equation to model the situation, we need to combine the fixed fee with the variable cost per minute.

The fixed fee of $10.00 stays the same each month, while the cost per minute is $0.05.

So, the equation to model the situation is:
Total phone bill = Fixed fee + (Cost per minute * Number of minutes)

We can express this equation using the variable 'm' to represent the number of minutes and 'b' to represent the total phone bill.

b = 10 + (0.05m)

Now, to determine the number of phone minutes Bob used in July, we need to solve the equation when the bill amount is $22.00.

22 = 10 + (0.05m)

Subtracting 10 from both sides:
12 = 0.05m

Dividing both sides by 0.05:
m = 12 / 0.05

Calculating this:
m = 240

Therefore, Bob used 240 minutes in July according to the given equation and bill amount.

440

440

10 + 0.05m = 22

0.05m = 12

m = ?
