Big Idea: Many real world situations can be modeled and predicted using mathematics.
__ Essential Question: What is the relationship between a table, a graph and an equation? __

** Karen wants to buy a stove from the Unlimited Store on an installment plan. The stove cost 305 dollars. **

 * A. Write an equation you could solve to find the number of months it will take Karen to pay for the stove.**

p = 15 x + 30
p = 15 x + 30 So it will take 18 months and 33 weeks to pay for Karen the stove.
 * B. Solve you equation by using the symbolic method. ** **How many months will it take Karen to pay for the stove?**

**__Follow up__**
a) 175 = 2.5x __175__ c)
 * 1.In a-d, use the symbolic method to solve the equation for x. Check your answers. **

2.5  11 70 x = 70 b) d) You could use a table.
 * 2. What other methods could you use to solve for x in the equations in question 1? **

I now understand how to make an equation on my data and i know how to
