AltEd is a startup that is in the initial stages of creating an online platform that will connect students on the autism spectrum who are unable to attend public schools with teachers who are interested in supplementing their income by teaching online part-time. Teachers are paid $100 per hour for their teaching sessions with the students. Parents have the option of booking either a one-hour or two-hour session with the teacher. The founder of AltEd expects that 80% of the bookings will be one hour and 20% will be two hours. AltEd charges the teacher 25% of each transaction. The founder of AltEd has established a minimum success criteria revenue goal of $3 million three years from now. How many transactions in year three will be needed to achieve this goal?
