Question

kennedy has a cell phone plan that charges $45 per month and includes 700 international minutes, but then charges $8 per minute for every minute used over the included minutes. how much would kennedy have to pay in a month if she used 24 minutes over the limit? how much would kennedy have to pay in a month if she went over by x minutes? total cost when over by 24 minutes: total cost when over by x minutes:

Explanation:

Step1: Identify base - cost and over - charge rate

The base cost per month is $45. The over - charge rate is $8 per minute for minutes used over the limit.

Step2: Calculate total cost for x minutes over the limit

The total cost $C$ when over by $x$ minutes is the sum of the base cost and the over - charge cost. The over - charge cost for $x$ minutes at $8$ dollars per minute is $8x$. So the total cost formula is $C = 45+8x$.

Step3: Calculate cost for 24 minutes over the limit

Substitute $x = 24$ into the formula $C = 45+8x$. We get $C=45 + 8\times24$. First, calculate $8\times24=192$. Then $45+192 = 237$.

Answer:

Total cost when over by $x$ minutes: $45 + 8x$
Total cost when over by 24 minutes: $237$
