Explanation:

Step1: Calculate cost for 23 - extra minutes

Cost for extra minutes = $2\times23 = 46$.
Monthly - base cost is $25$.
Total cost = base cost+cost for extra minutes.
Total cost = $25 + 46$.

Step2: Calculate total cost

$25+46=71$.

Step3: Find formula for $x$ extra minutes

Cost for $x$ extra minutes is $2x$.
Monthly - base cost is $25$.
Total cost when over by $x$ minutes is $25 + 2x$.

Answer:

Total cost when over by 23 minutes: $71$
Total cost when over by $x$ minutes: $25 + 2x$
