Answer:
3
Explanation:
Data provided in the question:
Sales for the last four months :
8, 10, 15, and 9 units
Last four forecast of sales:
9, 11, 8 and 12 units
Now,
The mean absolute deviation (MAD) value of these forecast will be calculated as:
MAD = [ ∑|Sales - Forecast sales| ] ÷ [ Total number of forecast ]
or
MAD =  [ |8 - 9| + |10 - 11| + |15 - 8| + |9 - 12| ] ÷ 4 
or
MAD = [ 1 + 1 + 7 + 3 ] ÷ 4 
or
MAD = 12 ÷ 4 
or
MAD = 3

Answer:
The demand for Post Raisin Brand cereal is: ELASTIC  
the demand for all types of breakfast cereals is: INELASTIC
Explanation:
To calculate the price elasticity of demand (PED) we can use the following formula:
PED = % change in quantity / % change in price 
- If PED > 1, the demand is price elastic
- If PED = 1, the demand is price unitary
- If PED < 1, the demand is price inelastic
*The PED always results in a negative number, e.g. price deceases, quantity increases, but for practical reasons we convert the negative number into a positive (we use absolute values) when we are determining the elasticity.

It will create duplicate expenses as there was an entry made for a new deposit.
The second problem will be as a result of the first one that, the income account will show duplicate income and correct the correct income will not be recorded.
