(I'll do my best to explain this:) ) if you put two triangles together they equal a rectangle. In other words if you split a rectangle from upper left corner to lower right corner you get two triangles. So if you multiply the triangle formula twice you get the rectangle formula.
There are 6 candles in each set and there are two sets of candle. All in all, there are 12 pieces of candle. To determine the price per candle, we just have to divide the total cost to the number of candles.
Price per candle = $36/12
Price per candle = $3

To solve this we are going to use the exponential function:
where
is the final amount after
years
is the initial amount
is the decay or grow rate rate in decimal form
is the time in years
Expression A
Since the base (0.95) is less than one, we have a decay rate here.
Now to find the rate
, we are going to use the formula:
*100%
*100%
*100%
5%
We can conclude that expression A decays at a rate of 5% every three months.
Now, to find the initial value of the function, we are going to evaluate the function at
We can conclude that the initial value of expression A is 624.
Expression B
Since the base (1.12) is greater than 1, we have a growth rate here.
To find the rate, we are going to use the same equation as before:
*100%
*100
*100%
*100%
12%
We can conclude that expression B grows at a rate of 12% every 4 months.
Just like before, to find the initial value of the expression, we are going to evaluate it at
The initial value of expression B is 725.
We can conclude that you should select the statements:
- Expression A decays at a rate of 5% every three months, while expression B grows at a rate of 12% every fourth months.
- Expression A has an initial value of 624, while expression B has an initial value of 725.
