### Cupcake Math

Raven Morris

Algebra 1 Pre-AP Accelerated

6th Period

What’s the Deal?
• Raven’s Cupcake Company ships cupcakes all over the country. There is a flat rate of \$2.00 for every order shipped, and cupcakes cost \$6.00 a dozen. What is the total cost if Shantaniatia orders three dozen cupcakes?
X and Y?
• Your ‘x’ value is the number of cupcakes that she purchases, which we already determined was three. So x=3.
• Your ‘y’ value is the total amount that the order will cost, which will be determined in a later slide.
• Equation: y=\$2.00+6x
Independent and Dependent?
• Our independent value is….the number of dozens of cupcakes purchased
• Our dependent value….is the total cost of the cupcake plus shipping
• So, the total amount required to purchase the cupcakes depends on the number of cupcakes purchased!
Function?
• In case you were wondering, yes, this is a function because it has independent and dependent values!!
Domain and Range!
• The domain is all of the possible x values. Lets just use…

D:{1,2,3,4,5,6,7}

The range is all the possible y values. To determine the y values, we have to use our formula, which is y=\$2.00+6x…

R:{\$8, 14, 20, 26, 32, 38, 44}

Continuous or Discrete?
• This domain is continuous, because you can get any number of cupcakes.
Function Notation

If this equation were written in function notation, it would look like this…

f(x)=\$2.00+6x

Equation Stated
• If we were to write this equation in what I like to call standard notation it would look like….

y= \$2.00+6x

Possible Outcomes
• Some of the possible outcomes to this equation are as follows…
Graph
• This is what some of the outcomes would look like on a graph…

Total Cost

Number of Cupcakes

So…
• Now that we know how to find our answer, we should be able to figure out that Shantaniatia will have to pay \$20.00 for her cupcakes and their shipping. We also hopefully learned a little more about functions from Raven Morris!
