Answer:
The price of the cake is $24 and the price of the Pie is $15
Step-by-step explanation:
Given
<em>Represent price of Cake with C and Price of Pie with P</em>
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

Answer:
$359.42
Step-by-step explanation:
The difference in the investment values can be computed by making use of the formulas for the account balance in each case.
compound interest: A = P(1 +r)^t . . . . interest at rate r compounded annually
simple interst: A = P(1 +rt) . . . . simple interest at rate r
__
The account earning simple interest will have a balance of ...
A = $8000(1 +0.12×3) = $10,880
The account earning compound interest will have a balance of ...
A = $8000(1 +0.12)^3 ≈ $11,239.42
The difference between the two investments is ...
$11,239.42 -10,880 = $359.42
gcf = 8 lcm= 5
gcf means greatest common facter. 8 goes into 8 1 time and 32 4 times. therefor 8 is the gcf. lcm means least common multiple. and 5 is the lowest number that goes into 20 and 40
