Question

question tanisha has a cell phone plan that charges $25 per month and includes 500 international minutes, but then charges $2 per minute for every minute used over the included minutes. how much would tanisha have to pay in a month if she used 23 minutes over the limit? how much would tanisha have to pay in a month if she went over by x minutes? total cost when over by 23 minutes: total cost when over by x minutes:

Explanation:

Step1: Identify the base - cost

The base - cost of the plan is $25 per month.

Step2: Calculate the cost for extra minutes

The cost per minute for minutes over the limit is $2. If she goes over by $x$ minutes, the cost for extra minutes is $2x$.
The total cost when over by $x$ minutes is the sum of the base - cost and the cost for extra minutes. So the total cost $C = 25+2x$.
When $x = 23$:
$C=25 + 2\times23$
$=25+46$
$=71$

Answer:

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