Answer:
250 minutes of calling will cost same using both plans.
$53
Step-by-step explanation:
Please consider the complete question.
A phone company offers two monthly plans. Plan A costs $23 plus an additional $0.12 for each minute of calls. Plan B costs $18 plus an additional $0.14 of each minute of calls. For what amount of calling do the two plans cost the same? What is the cost when the two plans cost the same?
Let x represent the number of call minutes.
The total cost of calling for x minutes using plan A would be cost of x minutes plus fixed charge that is
.
The total cost of calling for x minutes using plan B would be cost of x minutes plus fixed charge that is
.
To find the number of minutes for which both plans will have same cost, we will equate total cost of x minutes for both plans and solve for x.







Therefore, calling for 250 minutes will cost same using both plans.
Upon substituting
in expression
, we will get:

Therefore, the cost will be $53, when the two plans cost the same.
2x + 9 = 43 This is the equation.
2x = 34 Subtract 9 from both sides.
x = 17 Divide both sides by 2.
