Answer:
The price of 17 minutes call = $4.25
Step-by-step explanation:
Given
- Minutes spent = 5 minutes
- Cost of 5 minute call = $1.25
Thus,
The unit rate can be calculated
Unit rate = $1.25 / 5 minutes
Unit rate = $0.25 per minute
So,
The price of one minute call = $0.25
The price of 17 minutes call = 0.25 × 17
= $4.25
Therefore, the price of 17 minutes call = $4.25
