"your long distance service provider charges you $.06 PER minute plus a monthly access fee of 4.95 for referring a friend,you receive $10 service credit this month.if your long-distance bill is 7.85,how many long-distance minute did you use"
21.5
To determine the number of long-distance minutes used, we need to subtract the service credit and the monthly access fee from the total bill and then divide the remaining amount by the cost per minute.
1. Subtract the service credit from the total bill:
Total Bill - Service Credit = $7.85 - $10 = -$2.15
Since the resulting amount is negative, it means that after considering the service credit, your total bill is actually a credit of $2.15.
2. Subtract the monthly access fee from the credit:
Credit - Monthly Access Fee = -$2.15 - $4.95 = -$7.10
After accounting for the monthly access fee, the remaining amount is -$7.10, indicating a credit of $7.10.
3. Divide the remaining credit by the cost per minute to find the number of minutes used:
Minutes Used = Remaining Credit / Cost per Minute = $7.10 / $0.06 = 118.33 minutes
Based on the calculations, you used approximately 118.33 long-distance minutes this month. Please note that it's rounded to the nearest whole number, so the actual usage may vary slightly.
To determine the number of long-distance minutes used, we need to follow these steps:
Step 1: Calculate the total monthly charges by subtracting the $10 service credit from the long-distance bill:
Total Monthly Charges = Long-distance bill - Service credit
= $7.85 - $10
= -$2.15 (negative value due to the service credit)
Step 2: Determine the effective monthly access fee by adding the monthly access fee and the remaining negative amount from step 1:
Effective Monthly Access Fee = Monthly Access Fee + Total Monthly Charges
= $4.95 + (-$2.15)
= $2.80
Step 3: Divide the effective monthly access fee by the cost per minute to find the total number of long-distance minutes used:
Total Minutes = Effective Monthly Access Fee / Cost Per Minute
= $2.80 / $0.06
≈ 46.67 minutes
Therefore, you have used approximately 46.67 long-distance minutes.
