A cell phone plan costs 28.70$ per month for minutes of talk time. It costs an additional $0.05 per minute for each minute over 700 minutes. To get e-mail access, it costs 30% of the price for 700 minutes of talk time. Your bill, which includes e-mail, is the same each month for months. The total cost for all months is $326.48. Write and solve an equation to find the number of minutes of talk time you use each month.

Total number of minutes= 6,483

Step-by-step explanation:

Giving the following information:

Fixed cost (700 minutes)= $28.7

E-mail= (28.7*0.3)= $8.61

Cost per minute (over 700)= $0.05

Total cost= $326.48

First, we establish the total cost formula:

Total cost= 28.7 + 8.61 + 0.05*x

x= number of minutes over 700

Now, we need to calculate the number of minutes over 700:

326.48= 28.7 + 8.61 + 0.05x

289.17=0.05x

5,783 = x

Total number of minutes= 700 + 5,783

Total number of minutes= 6,483

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
