Ravi is comparing the costs of long distance calling cards. To use card A, the cost is $0.50 to connect and then $0.05 per minute. To use card B, it costs $0.20 to connect and then $0.08 per minute. For what number of minutes does it cost the same amount to use each card for a single call?

minutes = x. .5 + .05x = .2 + .08x. solve for x.
