Let's analyze the problem step-by-step.
Given:
- Monthly fixed cost = 00 (likely missing a digit, but let's assume it's 0 for now)
- Cost per minute = p8
- Total bill = p1,420
Goal:
Find the number of minutes used.
Solution:
If the monthly fixed cost is 0, then:
Total bill=(cost per minute)×(number of minutes)\text{Total bill}=(\text{cost per minute})\times (\text{number of minutes})Total bill=(cost per minute)×(number of minutes)
1420=8×minutes1420=8\times \text{minutes}1420=8×minutes
minutes=14208=177.5\text{minutes}=\frac{1420}{8}=177.5minutes=81420=177.5
Interpretation:
- You used 177.5 minutes to get a bill of p1,420 at p8 per minute.
- If the fixed monthly cost is not zero, please provide the correct amount to adjust the calculation.
If you clarify the fixed monthly cost, I can give a more precise answer!
