20(0.1) + 0.75 = ?
To find the cost of a 25-minute call from Detroit to Paris, we need to consider both the initial 5 minutes and the additional minutes beyond that.
First, let's calculate the cost for the initial 5 minutes of the call. We are given that the price for the first 5 minutes is 75 cents. So, the cost for the initial 5 minutes is $0.75.
Next, let's calculate the cost for the remaining 20 minutes of the call. We are told that each additional minute or fraction thereof costs 10 cents. Since there are 20 additional minutes, the cost for these minutes would be 20 * $0.10 = $2.00.
To find the total cost of the entire call, we add the cost of the initial 5 minutes to the cost of the remaining 20 minutes:
Total cost = Cost for initial 5 minutes + Cost for additional 20 minutes
= $0.75 + $2.00
= $2.75
Therefore, the cost of a 25-minute call from Detroit to Paris using this particular phone company is $2.75.
