A storage gives every 42nd customer a $42 gift certificate.Every 30th customer gets a $30 gift certificate. What number customer will be the first to receive both types of gift certificates?

The answer would be customer 72, since the sum of the numbers 30 and 42 would equal 72. So customer 72 would receive both gift certificates.
