Final answer:
The equation can then be solved to find the value of 'm', representing the minutes of talk time. In this case, the answer is 68 minutes of talk time each month.
Step-by-step explanation:
To find the minutes of talk time you use each month, we can set up an equation based on the given information. Let's assume that the number of minutes of talk time you use each month is represented by 'm'.
The total cost for all 6 months is $195.12, which is equal to the sum of the monthly costs. Each month, the cost of the cell phone plan is $23.70 for 700 minutes of talk time, plus an additional $0.06 per minute for each minute over 700 minutes. Additionally, to get email access, it costs 20% of the price for 700 minutes of talk time.
Based on this information, the equation is: 195.12 = 6(0.06m + 23.70 + 0.20(23.70))
To solve the equation, we can simplify it: 195.12 = 6(0.06m + 23.70 + 4.74)
195.12 = 6(0.06m + 28.44)
Divide both sides of the equation by 6, we get: 32.52 = 0.06m + 28.44
Subtract 28.44 from both sides of the equation, we get: 32.52 - 28.44 = 0.06m
4.08 = 0.06m
Divide both sides of the equation by 0.06, we get: m = 68
Therefore, you use 68 minutes of talk time each month.
