My website provides photographer services. For example, an hour costs $150 to book me and I have to deliver 10 photos. 2 hours cost $300 and i have to deliver 20 photos. Is there an attribute that increase with the price so that if a customer selects 5 hours, it should automatically display $700 and also display that i have to deliver 50 photos. Please see screenshots.
If not possible, is there a workaround? Thank you.
