METHOD 1
f(3) = 20
f(4) = 30
f(5) = 42
f(6) = 56

rate of change
f(4)-f(3)=10
f(5)-f(4)=12
f(6)-f(5)=14

then the average of change is 10+12+14 /3 = 12


METHOD 2 --- faster

rate of change = f(6)-f(3) / 6-3
= (36+18+2)-(9+9+2) / 3
= 36/3 = 12

The gross profit margin is calculated using the following rule:
gross profit margin = total profit / total sales

Now, we need to get the values of total profit and total sale:
total profit = <span>9*8-(40+8)=24$
total sales = 9*8 = 72$

Now, we will substitute in the above equation:
gross profit margin = 24/72 = 1/3 = 0.3333334
% = 0.33333334*100 = 33.3334%</span>
