A cleaning service charges $⁢80 per hour for their basic package. They decide to mark up their price by (1)/(2) If they book 50 hours of cleaning services, what is the total revenue from these bookings?

A markup of 1/2 means increasing the $80 hourly price by 50%. The increase is $80 × 1/2 = $40, so the marked-up rate is $80 + $40 = $120 per hour. For 50 hours, the total revenue is $120 × 50 = $6,000, which is choice B.
