Janice needs to figure out her cell phone bill. She is charged a monthly flat fee of $45. She is also charged $0.25 per minute. How many minutes dis she use if her cellphone bill was $145. write an equation and solution
45 + 0.25m = 145
To determine how many minutes Janice used, we can set up an equation based on the information given.
Let's assume Janice used x minutes.
The equation can be written as follows:
45 + 0.25x = 145
Explanation:
The flat fee of $45 is added to the cost per minute of $0.25 multiplied by the number of minutes used (x). The total cost should equal $145.
Now, we can solve the equation to find the value of x, representing the number of minutes Janice used:
0.25x = 145 - 45 (subtract 45 from both sides)
0.25x = 100 (simplify)
x = 100 / 0.25 (divide both sides by 0.25)
x = 400 (simplify)
Therefore, Janice used 400 minutes.
