Question 776795: With an AT&T calling plan, you pay $4.95 per month plus 7 cents a minute of talk time. In July, the total cost of both the monthly fee and talk time was $29.45. Determine the number of minutes of talk time used in the month of July. Identify a variable and write an equation.
I have the answer of 350 minutes.
I took the total ($29.45)-monthly rate ($4.95)=$24.50 and then I divide it by 7 to equal 350. What is the proper equation to use in this question.
Thank you ahead of time!!
