To find the possible number of minutes Yoko has used her phone in a month, you can set up an inequality based on the given information.

Let's denote the number of minutes Yoko has used her phone as "m."

She pays a monthly fee of $12, and she pays an additional $0.05 per minute. So, the total cost for her phone service in a month can be represented as:

Total Cost = Monthly Fee + (Cost per Minute * Number of Minutes)

Total Cost = $12 + ($0.05 * m)

According to the problem, the total cost is $71.65. So, we can write the equation:

$12 + ($0.05 * m) = $71.65

Now, let's solve for m:

$0.05 * m = $71.65 - $12

$0.05 * m = $59.65

Now, divide both sides by $0.05 to find the number of minutes (m):

m = $59.65 / $0.05

m = 1193

So, the possible number of minutes Yoko has used her phone in a month is 1193 minutes. However, since she pays $0.05 per minute, if she uses more than 1193 minutes, her total cost will exceed $71.65. Therefore, the inequality for m is:

m ≤ 1193
