Final answer:

The costs of both plans are equal when there are 175 minutes.

Step-by-step explanation:

To find the number of minutes where the costs of both plans are equal, we need to set up an equation.

Let x be the number of minutes.

For Plan A:

Cost = $8.00 (monthly fee) + $0.18 (per long-distance minute)x

Cost of Plan A = $8.00 + $0.18x

For Plan B:

Cost = $15 (monthly fee) + $0.14 (per long-distance minute)x

Cost of Plan B = $15 + $0.14x

To find the number of minutes, we'll equate the costs of both plans:

$8.00 + $0.18x = $15 + $0.14x

Solve for x:

$0.18x - $0.14x = $15 - $8.00

$0.04x = $7.00

x = $7.00 / $0.04

x = 175

The costs of both plans are equal when there are 175 minutes.
