Joel Parkerelli owns a large-scale surfing school Radical Surfing School (RSS) that operates in his friend Kelly Slateropoulos wave pool. RSS has many students. To become a student, individuals need to sign up for membership, of which there are three levels: Gold, Silver and Bronze.

Joel has come to you to help him prepare his budgets for the next 12 months, ending 31 December 2020.

Based on expert marketing analysis, the number of memberships sold next year is expected to be 100 Gold, 200 Silver and 400 Bronze, and the membership fee is $8000, $4000 and $2000, respectively.

Gold members have 24-hour-a-day access, including to night-surfing facilities; Silver members have daily access from 9 a.m. to 5 p.m., and Bronze members have access on weekends between 11 a.m. and 4 p.m.

From this, create a sales budget for the year ending 31 December 2020
