Question 3
a). Calculation of Kathy's yearly revenue
Total revenue = Number of pupils x charge per pupil
Total revenue = 400 x 200
Total revenue = $ 80, 000
b). Calculation of Kathy's avearge total cost
Average total cost = highest expense + lowest expense
2
Average total cost = ((400 x 20) + (400 x 30))
2
Average total cost = 8,000 + 12,000
2
Average total cost = $10,000
c). Kathy's profit
Yes! Kathy makes a huge profit
Profit = ( Revenue - Total expenses )
Profit = ( $ 80,000 - $ 10,000)
Profit = $70,000
Question 4
Break even point =Fixed cost/ (selling price -cost)
Fixed cost = $ 750
Selling price = $ 1.5
Cost = $0.50
Break even point = $750
($ 1.5 - $ 0.5)
Break even point = $750
1
Break even point = 750
