Average cost is the ratio of total cost and the number of goods. Hence, for this problem:
Average cost=
So,
Where A(b)= average cost, c(b)= total cost and b= number of candles.
Since, c(b)=250+3b
So, the average cost is
Answer:
17 X 8 = 136^
area of a triangle
0.5 X b X h
0.5 X 8 X 17 = 68 cm^
136 - 68 = 68 cm^
total shaded area = 68 cm^
