Final answer:
To find the amount of calling for which the two plans cost the same, set up an equation using the costs of the two plans and solve for the number of minutes of calling. For 1200 minutes of calling, both Plan A and Plan B will cost the same amount.
Step-by-step explanation:
To find the amount of calling for which the two plans cost the same, we can set up an equation and solve for the number of minutes.
Let's assume the number of minutes of calling is represented by x.
For Plan A, the cost can be calculated as $24 + $0.08x.
For Plan B, the cost can be calculated as $0.10x.
We can set up the equation $24 + $0.08x = $0.10x and solve for x:
$24 + $0.08x = $0.10x
$24 = $0.02x
x = $24/$0.02
x = 1200 minutes
Therefore, for 1200 minutes of calling, both Plan A and Plan B will cost the same amount.
