A cell phone company charges a flat rate of $4.75 per

month, with an additional charge of $0.19 per minute. How

many minutes did Alexandra talk on her cell phone if her

monthly bill was $27.55?

120 minutes

Step-by-step explanation:

you take 27.55 and subtract the flat rate of 4.75 and then divide that answer by. 19

120 minutes

Step-by-step explanation:

The total bill in the month was $27.55, if you take the monthly rate and subtract it from the total you get:

$27.55 - 4.75 = $22.80

Then divide that amount by the rate of minutes to get the amount of minutes:

22.80/.19 = 120 minutes
