Cakes sold = 8
Pies sold = 14
Required
Determine C and P
To represent the cakes and pies sold, we have the following expression
Substitute 9 + P for C
Open the bracket
Collect Like Terms
Divide both sides by 22
Recall that
<em>Hence, the price of the cake is $24 and the price of the Pie is $15</em>

x = -1.14 or -13.14
Explanations:The given equation is:
Find the half of 12, and add the square to both sides of the equation.
That is add 6² to both sides
Find the square root of both sides:
x = -1.14 or -13.14
