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?

answer

total cost when over by 23 minutes:

total cost when over by x minutes:

Explanation:

Step1: Calculate cost for 23 extra minutes

The extra minutes cost $\$2$ per minute. For 23 minutes, the extra cost is $23 \times 2 = 46$.

Step2: Add base cost to extra cost

The base monthly cost is $\$25$. So total cost is $25 + 46 = 71$.

Step3: Generalize for $x$ extra minutes

Extra cost for $x$ minutes is $2 \times x = 2x$. Total cost is base cost + extra cost: $25 + 2x$.

Answer:

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