1a) Create a t-chart showing how many baseballcards Jack has at the end of the next 4 months.

1b) Create an algebraic formula based upon the problem above
180+25*n (month)

1c) If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month, how many baseball cards will Jack have when he turns 12?
Jack will have 1380 baseball cards.

1) What is the difference between an algebraic expression and an equation? Give an example of both an expression and an equation.
The difference is that equation is that the variable is only one number and in an expression it can be any number.

2)What is a variable and why do we use one in algebra?
A variable is a letter that represents a number. We use them in algebra because they allow instructions to be specified in a general way.

3)Solve for N
-4 -4

4)Solve the following equations. Show all of the steps that are needed.
8/8 11/8
n =1.375


I will be first at the 2000m line.

nice graph leslie. You have some problems with question 4.

You didn't solve the second part of question 3. Yes a triangle is = 5 but what is N in the second diagram equal to?
