<u>Answer:</u>

22

<u>Step-by-step explanation:</u>

We know that it charges $0.46 to make a long distance phone call for the first minute and $0.37 for each additional minute.

The total charge for the call was $8.23 and we are to find the total number of minutes of the call.

So firstly, we will subtract the cost of the first minute from the total cost:

$8.23 - $0.46 = $7.77

Now divide this cost by per minute cost of additional minutes:

7.77 / 0.37 = 21

So adding back the first minute of the call, we get a total of 22 minutes.
