Answer: $10.20
Step-by-step explanation:
Let's first collect the information from the word problem.
<h3><em>We are told:</em></h3>
- Bought 15 pies and 7 cake slices
- Total cost was $55.22.
- Pies cost
as much as a slice of cake
<h3><em>We need to solve for:</em></h3>
- Total cost of 1 pie and 2 cake slices
1. Create an equation/expression:
To solve the problem, we need to find the price of a pie and cake slice.
Using the information gathered, the equation is:

<em>x = the cost of the slice of cake.</em>
<em />
2. Simplify/Solve

- Great! we have the price of a slice of cake. ($4.25)
Remember that the pie is
of a slice of cake, so now find the price of the pies.
Pie = 
Pie = $1.70
- Awesome! We know a slice of cake costs $4.25 and a slice of pie costs $1.70.
3. Check your work!
<em>Check to make sure the math is done correctly!</em>

Good! It is verified that our calculations are correct.
4. Solve!
1 pie and 2 cakes cost: 
- $10.20 is our final answer!
- Hope this helped!~~ -Astro
Two bags, $21 each means 2 x 21 = $42 total. 42/3 = $14
Answer:
The Answer is: B.
Step-by-step explanation:
The form of the equation is:
f(x) = ab^x
When b is greater than 0 and less than 1, the function is an Exponential Decay Function.
B. is f(x) = (.08)^x
In this case, a = 1
