A landscaping service charges $⁢150 per hour for their premium package. They decide to offer a discount of (1)/(5) on the original price. If they book 40 hours of landscaping services, what is the total revenue from these bookings?

The discount is 1/5 of $150, which is $30 per hour. The discounted rate is therefore $150 − $30 = $120 per hour. For 40 hours, the revenue is 40 × $120 = $4,800, so the correct choice is 4 dollars, 800.
