Each month, Alex’s cellphone plan costs
$15, plus $0.10 per minute of use.
Which graph could represent Alex’s total
monthly cost?

Answer 1

Answer:

Graph-d

Step-by-step explanation:

We are given that,Each month, Alex’s cellphone plan costs $15 and additional 0.10 per minute of use. The equation that would represent Alex's total monthly costs would be linear equation (equation of a line). Linear equation has the following form:

$y = mx + b$

in this case,

• m represents the cost of Alex's per minute of use
• b represents the initial costs of Alex's cellphone plan
• m represents the number of minutes
• y represents the amount of total monthly cost

Since Alex’s cellphone plan initially costs $15, b would be 15 . Again he has to pay an additional cost of $0.10 per minute of use. hence, m would be 0.10 or ⅒ . Therefore our equation of line is

• ⇒$y=\dfrac{1}{10}x+15$

In conclusion

Graph d represents Alex’s total monthly cost
