Let's call it "capacity".
amount_to_bill = flat_fee +
(CASE WHEN ((capacity > 10) AND (capacity <= 20))
THEN (capacity - 10)*rate1
WHEN (capacity > 20) THEN 10*rate1
ELSE 0
END) +
(CASE WHEN ((capacity > 20) AND (capacity <= 50))
THEN (capacity - 20)*rate2
WHEN (capacity > 50) THEN 30*rate2
ELSE 0
END) +
(CASE WHEN (capacity > 50) THEN (capacity -
50)*rate3
ELSE 0
END) ;
HTH,
